"John Russell got his first guitar in 1965 while living in Kent and began to play in and around London from 1971 onwards. An early involvement with the emerging free improvisation scene (from 1972) followed, seeing him play in such places as The Little Theatre Club, Ronnie Scott's, The Institute of Contemporary Arts, The Musicians' Co-Op and the London Musicians' Collective. From 1974 his work extended into teaching, broadcasts (radio and television) and touring in the United Kingdom and, ever extensively, in other countries around the world . He has played with many of the world's leading improvisers and his work can be heard on over 50 CDs and albums. In 1981, he founded QUAQUA, a large bank of improvisers put together in different combinations for specific projects and, in 1991, he started MOPOMOSO which has become the UK's longest running concert series featuring mainly improvised music."

"John Butcher's work ranges through improvisation, his own compositions, multitracked pieces and explorations with feedback and extreme acoustics.Originally a physicist, he left academia in '82, and has since collaborated with hundreds of musicians - Derek Bailey, John Tilbury, John Stevens, The EX, Akio Suzuki, Gerry Hemingway, Polwechsel, Gino Robair, Rhodri Davies, Okkyung Lee, John Edwards, Toshi Nakamura, Paul Lovens, Eddie Prevost, Mark Sanders, Christian Marclay, Otomo Yoshihide, Phil Minton, and Andy Moor - to name a few.

He is well known as a solo performer who attempts to engage with the uniqueness of place. Resonant Spaces is a collection of site-specific performances collected during a tour of unusual locations in Scotland and the Orkney Islands.His first solo album, Thirteen Friendly Numbers, includes compositions for multitracked saxophones, whilst later solo CDs focus on live performance, composition, amplification and saxophone-controlled feedback.

HCMF has twice commissioned him to compose for his own large ensembles. Other commissions include for Elision (Australia), the Rova (USA) & Quasar (Canada) Saxophone Quartets, reconstructed Futurist Intonarumori (USA), "Tarab Cuts" (based on pre-WWII Arabic recordings, and shortlisted for the 2014 British Composer's Award) and "Good Liquor .." for the London Sinfonietta. In 2011 he received a Paul Hamlyn Foundation Award for Artists.

Recent groupings include The Apophonics with Robair and Edwards, Anemone with Peter Evans, Plume with Tony Buck & Magda Mayas and a trio with Okkyung Lee & Mark Sanders.Butcher values playing in occasional encounters - ranging from large groups such as Butch Morris' London Skyscraper and the EX Orkestra, to duo concerts with David Toop, Kevin Drumm, Claudia Binder, Paal Nilssen-Love, Thomas Lehn, Fred Frith, Keiji Haino, Ute Kangeisser, Matthew Shipp and Yuji Takahashi."

"Started on clarinet after seeing the Benny Goodman Story, a year later aged 16 my 1st jazz gig on a float through Kingston(Surrey). where I had begun a 4 yr fine art diploma course. In 1960 bought a nice piano at auction for £3 having heard Errol Garner Red Garland and Dave Brubeck (pre Take 5). Played piano in a no of Jazz groups in the '60s including Gare/Prevost quintet - involvement shortlived after leaving piano parts on car roof (I like to think this spurred Eddie on to 'dot free' improvisation). Joined the R+B and Jazz group; the Sidewinders with Marc Charig which was chosen to back (little) Stevie Wonder's 2nd British tour. His MD didn't read music so the band's rehearsals involved learning the program by ear from 45's. We played venues such as the Cavern Club, the Marquee, Klooks Kleek (right next to Decca Studios my future employer!)

Having played with Mike Osborne at home earlier in the decade, met him again at drummer Terry(Nillson)Love's Redhill Jazz club where Terry and I were in the house band. Mike guested there regularly he asked me to play some gigs as a quartet c1967/8 . Also joined another regular group there; the London based unruly Mingus influenced experimental 'Hotshot delivery Service' that often sported 2 bass players and drummers incl Dave Wickens . It was here that I did my first purely free improvisation in public as member of 'Free Root' trio in 1968. That year went to one of the first Barry Jazz course's and encountered pianist John Burch and his then famous 'Jazz blackboard' and Derek Bailey whose music room unfortunately lacked a piano! Other pupils on the course incl Keith Tippet, Nick Evans and Marc C. and here the seminal KT band was born I believe.

The early 70's was mostly spent composing and playing for various Jazz groups in and around London that included Dick Pearce, John Williams, Maggie Nicolls, Harry Smith etc. In 1973 composed and organized a piece '(Underneath)The Archers' possibly as a belated revenge for that soap replacing 'Dick Barton Special agent' when I was a kid. A kind of an 'everyday story of rustic looking musos' these incl. Howard Riley, Henry Lowther, Ron Mathewson, Harry Smith, Alf Waite etc in a big group, plus tape loops, large bucket of cow dung with stirrer, Milkmaid and yoke, hay etc .

Meeting Richard Beswick, a trainee producer at Decca' connected me to a another side of free impro in the forms of Tony Wren and Phil Wachsmann and Bead records. Had also got into to electronic treatments and synths and augmented their group 'Chamberpot'. Later in the early 80's met John Butcher in one of John Williams's larger jazz ensembles and many improvisers in other situations: Mick Beck, Will Evans, Sue Farrar. Paul Hession, Parney Wallace, and Hugh Metcalf to name but a few. Later, collaborations again with Phil Wachsmann as well as with Chris Burn dominated a lot of my musical activities in the '90s ; and presented opportunities to record, and to play in Europe and N.America ; and to work in bands such as King Ubu Orchestru that included Wolgang Fuchs and Dorothea Schurch, the Milo Fine group as well as the various permutations of Chris B's Ensemble that included Jim Denley, John Russell, Stevie Wishart. This group collaborated with the likes of Lol Coxhill, Derek B, Evan Parker, I also performed with the Mhu Mhu Orchester with Pauls Lytton and Rutherford and Johannes Bauer. Became a regular performer at the LMC and legendary Red Rose Club and also Hugh M's Klinker club. Other musical encounters variously included Simon Rose, Venessa Macness

Occasional diversions into other musical situations included being the unenthusiastic half of a Jacques Brell tribute duo , Driving legendary Jazz pianist Joe Albany on tour around England, and receiving an ACGB grant to make an electronic exploration of the piano.

Towards the end of the decade played in N16 IMPRO 21 with Peter Cusack ; 'Huchinsack' duo and was privileged to appear in the London Contemporary Piano Festival in 1998 alongside Stan Tracy, Michael Finnissey, Mervn Afrika, Rene Reznek.

The new millennium saw me continue in Ensemble as well as work with smaller groups particularly Duos with Chris B and Phil W and subsequent albums with both. Played my debut solo piano set at Mopomoso at the Vortex recently where I've performed many times. This appeared to go down well, though generally I feel more inclined to musical collaborations, though a solo piano Cd with or without electronics could be in the pipeline. Other projects for the near future include a 4 hands 1 piano duo, a Piano /Violin/ Cello trio, and possibly recording improvisations to a piano roll."

"Steve Beresford (born 1950) is a British musician who graduated from the University of York. He has played a variety of instruments, including piano, electronics, trumpet, euphonium, bass guitar and a wide variety of toy instruments, such as the toy piano. He has also played a wide range of music. He is probably best known for free improvisation, but has also written music for film and television and has been involved with a number of pop music groups.

Beresford played in Derek Bailey's Company events and in the groups Alterations with David Toop, Terry Day and Peter Cusack, and the Three Pullovers with Nigel Coombes and Roger Smith. He was also a member with Gavin Bryars and Brian Eno of the Portsmouth Sinfonia.

Beresford has continued to play free improvisation with a number of prominent musicians, including Evan Parker, Lol Coxhill, John Zorn, and Han Bennink. He has collaborated extensively with Swiss-American artist/musician Christian Marclay and is an active member of the long-standing London Improvisers Orchestra.

From 2010 he performed various pieces by John Cage, including Indeterminacy with Tania Chen and comedian Stewart Lee, and a performance with Ilan Volkov at The BBC Proms 2012 at The Royal Albert Hall in London.

He has also worked with a number of popular musicians, including Ray Davis, The Slits, Frank Chickens, Ted Milton and The Flying Lizards. In 2015 he performed a duoproject with the upcoming Norwegian singer Natalie Sandtorv at the Blow Out! festival in Oslo, Norway.

He was awarded a Paul Hamlyn Award for Artists in 2012. He is a senior lecturer on the Commercial Music course at University of Westminster.

Beresford's music and his teachings have inspired the musical community in the UK for over a decade. British songwriter and performer Katy Carr cites Steve Beresford's lectures on musical themes associated with Free improvisation, Experimental music, John Cage, musique concrète, Diamanda Galás and The Slits as a source of initial inspiration with regards to the creation of her debut album, Screwing Lies released in 2001."

"Roger Turner (born 1946, Whitstable, England) is an English jazz percussionist. He plays the drumset, drums, and various percussion, and was brought up into the jazz and visual art cultures inhabited by his older brothers, playing drums from childhood in informal jazz contexts.

Turner studied English literature and contemporary philosophy at Sussex University, playing with Chris Biscoe for the British Council in 1968, a first concert in improvisation. His move to London gave him contact with the first and second generation improvisers and he began to play primarily with Lol Coxhill, Gary Todd, John Russell, Hugh Davies, Steve Beresford, and Phil Minton.

In the years immediately after 1974 his work was primarily concentrated on opening the way to a more personal percussion language. This was also a period of intense collaborations that structured many of his future approaches to music-making and saw the formation of two long-lasting acoustic duos with Phil Minton and with John Russell. Recordings of these duos document an extreme attention to timbre and pitch, as well as a constantly shifting speed that typified much of his work at the time. The duo with Minton toured extensively throughout Europe, USA and Canada.

In 1979 he established CAW records with John Russell and Anthony Wood, and recorded the solo album The Blur Between focussing on single surface improvisations: a linear and reduced equipment approach he had started using with Carlos Zingaro and others in live performances.

In addition to forming Trump music with Gary Todd to promote improvised music in London, he also involved himself in formative activities of the London Musicians Collective during this period. He was awarded Arts Council of Great Britain bursaries for solo percussion in 1980, and in 1983 for investigation into percussion with electronics. Extensive festival and club solo work followed, including the Bracknell Jazz Festival and the Brussels Festival of Percussion.

In 1982 the trio The Recedents was formed with Lol Coxhill and Mike Cooper exploring the possibilities of electro-acoustic music, in which Turner initially played drumset and EMS Synthi A as a means of bending the sounds of various metal percussion instruments. This group, still existing, mixes song, jazz, punk/thrash, with acoustic detail in always shifting sonorities, and has worked throughout Europe, Canada and the UK, also recording for the French Nato label. Involvements with experimental rock musics and open-form song included extensive work in duo with Annette Peacock 1983-5, with whom he toured in Europe and Scandinavia. They recorded the album I have no feelings for Ironic.

In 1984-5, he was invited for workshop residences at Alan Silva's Institute Art Culture Perception in Paris, where long-term collaborations with Alan began, culminating in The Tradition Trio with Johannes Bauer. This group was central to his explorations of forms of free jazz, an interest that has seen him working with musicians on both sides of the Atlantic (including Elton Dean, Irene Schweizer, Cecil Taylor, Roy Campbell, Henry Grimes, The Wardrobe Trio and Charles Gayle).

Since the early 1980s his work has focussed on numerous projects with improvising musicians and groups, touring Europe, Australia, USA and Canada. Perhaps the most important of the later groups would be Konk Pack, formed in 1997, with Tim Hodgkinson and Thomas Lehn, a group whose use of volume and sense of detail continues the exploration of an electro-acoustic dynamic that forms one of his main musical concerns. This group has toured extensively in Europe and USA.

He forged working relationships with Japanese musicians over the years: in the 1980s with Toshinori Kondo in the trio with John Russell, but since the mid-1990s in concerts and recordings with guitarist Kazuhisa Uchihashi in Austria, Japan, and U.K, and in the recent (2009) Hana-Bi three-day event in London that included the guitarist and the pianist Chino Shuichi.

An active involvement in visual art has always been in dialogue with his music, and an inspiration for it. In the forefront of this is his work with Susan Turcot (the investigation/documentation of music and sound-drawing both in Europe and Canada-including the Being Rich box collection --, and music for her 2008 animation film Bitumen, Blood, and the Carbon Climb.

His music for dance/performance includes work with Alexander Frangenheim's Concepts of Doing, Stuttgart ; Carlos Zingaro's Encontros projects in Lisbon and Macau; and most recently in the Josef Nadj production etc.etc. (premiered Vandeouvre, France, 2008) and which is a continuing involvement.

In March 2009 he was invited to travel and perform on the Arctic island Svalbard, and was also invited to attend and play in the Comprovise event in Cologne, Germany in June 2009, set up to examine any possible relationship between improvisation and composition.

Turner's music-making with international improvisers in ad hoc and group collaborations have since the 1970s to the present day included Toshinori Kondo, Derek Bailey, Fred Frith, Evan Parker, William Parker, Cecil Taylor, Otomo Yoshihide, Shelley Hirsch, Joelle Leandre, Keith Rowe, Ab Baars, Barry Guy, Barre Philips, Henry Grimes, Paul Rutherford, Gunter Christmann, Marilyn Crispell, Irene Schweizer, Frederik Rzewski, and Malcolm Goldstein."

"Alan Tomlinson was born in Manchester and studied trombone at the City of Leeds College of Music. He has been actively improvising since the early 1970s and was a member of I.L.E.A's Cockpit Theatre Music Ensemble, Tony Oxley's Angular Apron, Barry Guy's London Jazz Composers Orchestra and the Ballet Rambert Orchestra.

He works with musicians including Jon Corbett, David Toop, Phil Minton and Paul Hession and has toured all over Europe and as far afield as North America and Siberia. He recorded the solo album 'Still Outside' in 1980 and more recently 'Trap Street', with Steve Beresford (electronics) and Roger Turner (percussion) which was released in May 2003 on Emanem."

"Eddie Prévost (Edwin John) (born Hitchin, Hertfordshire, England, 22 June 1942) is an English percussionist noted for founding and participating in the AMM free improvisation group.

Of Huguenot heritage, Prévost's silk weaving ancestors moved to Spitalfields in the late 17th century. Brought up by single parent mother (Lilian Elizabeth) in war-damaged London Borough of Bermondsey. He won a state scholarship to Addey and Stanhope Grammar School, Deptford, London, where to-be drummers Trevor Tomkins and Jon Hiseman also studied. Music tuition, however, was limited to singing and general classical music appreciation. Enrolled in the Boy Scouts Association (19th Bermondsey Troop) to join marching band. As a teenager began to get involved with the emerging youth culture music; skiffle, before being introduced to a big jazz record collection of a school friend with rich parents. With a bonus from the florist, for whom Prévost worked part-time after school, purchased his first snare drum from the famed Len Hunt drum shop in Archer Street (part of London's theatre land).

After leaving school at sixteen Prévost was employed in various clerical positions whilst continuing his musical interests. Although, by now immersed in the music of bebop, his playing technique was insufficient for purpose. New Orleans style jazz ('trad') offered scope for his growing musical prowess. He played in various bands mostly in the East End of London. It was during a tenure with one of these bands he met trumpeter David Ware, who also shared a passion for the hard-bop jazz music. In their early twenties they later formed a modern jazz quintet which ultimately included Lou Gare, who had recently moved to London from Rugby and was a student at Ealing College of Art and a member of the Mike Westbrook Jazz Orchestra.

AMM was co-founded in 1965 by Lou Gare, Eddie Prévost and Keith Rowe. They were shortly joined by Lawrence Sheaff. All had a jazz background. They were, however, soon augmented by composer Cornelius Cardew. Thereafter, Cardew, Gare, Prévost and Rowe remained as basis of the ensemble until the group fractured in 1972. Other more formally trained musicians were to enter the ranks of AMM after Cardew's departure. Those to make significant contributions were cellist Rohan de Saram and, in particular, pianist John Tilbury. The latter was a friend and early associate of Cardew and later became his biographer.

In contrast to many other improvising ensembles, the core aesthetic of the ensemble is one of enquiry. There was no attempt to create a spontaneous music reflecting, or emulating, other forms. The AMM sound-world emerged from what Cardew referred to as "searching for sounds". For Prévost, the following would become the core formulation which he would explore during his subsequent musical career and explain and develop in various writings (see bibliography) and workshop activities.

We are "searching" for sounds and for the responses that attach to them, rather than thinking them up, preparing them and producing them.

In the 1980s, in response to various workshops and lectures, Prévost first formulated the twin analytical propositions of heurism and dialogue as defining concepts for an emergent musical philosophy, whilst acknowledging Cardew's construction (above). This line was explored and constantly redefined much through the London workshop experience, as his articles and his books show. (see below: The London Workshop). His 2011 book - The First Concert: an Adaptive Appraisal of a Meta Music - is described as a view "mediated through the developing critical discourse of adaptionism; a perspective grounded in Darwinian conceptions of human nature. Music herein is examined for its cognitive and generative qualities to see how our evolved biological and emergent cultural legacy reflects our needs and dreams. This survey visits ethnomusicology, folk music, jazz, contemporary music and "world music" as well as focusing upon various forms of improvisation - observing their effect upon human relations and aspirations. However, there are also analytical and ultimately positive suggestions towards future metamusical practices. These mirror and potentially meet the aspirations of a growing community who wish to engage with the world - with all its history and chance conditionals - by applying a free-will in making music that is creative and collegiate." (back cover of First Concert)History with AMM

When, in the early 1970s, Cardew and Rowe began to devote their time and energy to espousing the political doctrine of an English Maoist party a fracture occurred in the ensemble leaving the rump of Lou Gare and Eddie Prévost, who continued in a duo form making various concerts and festival appearances and leaving a legacy of two recordings. At the end of the decade a rapprochement was attempted and for a short while the quartet began playing together again. It did not last. Lou Gare departed and moved from London to Devon. While Cardew's commitment to politics made his complete withdrawal inevitable. It was during this period Prévost took an Honours Degree at Hatfield Polytechnic, exploring and developing his interests in history(especially East Asian) and philosophy. Musically, this left Rowe and Prévost playing together. Their recording for German ECM label "It had been an ordinary enough day in Pueblo, Colorado" is the single example of their duet period. By the late 1970s a reawakened association with John Tilbury was cemented into his permanent place in AMM. He is featured on all subsequent AMM performances and recordings (as is Prévost). In 2002 a more lasting schism occurred leading to Rowe departing from AMM and leaving Tilbury to continue with Prévost.Percussion

The investigative dynamic of AMM leads a musician to seek out new material. It is the fabric and constitution of stuff that is considered as more important than any historical or cultural heritage. It is Prévost's constant exploration's that has produced the range of sounds associated with his work, particularly within AMM and its extension to the many workshop ensembles. This philosophy leads to what Seymour Wright has so aptly described as the "awkward wealth" of investigation.(citation) It is a position of constant examination and artistic redress.Drumming

Drumming with AMM was principally replaced by discreet percussion work which by and large relied on sound and texture rather than rhythm. At the time of the Gare/Prévost period this position was reviewed. However, it was plain the AMM aesthetic, characteristic of the early formative period, was to have its effect. The "searching" method prevailed. And, whereas a saxophone and drums duet led to a more jazz-like expectation (amplified by Gare's reversion to a more rolling and modal post-Rollins kind of approach). Prévost's playing was noted to have acquired some unusual qualities. This lead one reviewer (Melody Maker) to remark in 1972: "His free drumming flows superbly making use of his formidable technique. It's as though there has never been an Elvin Jones or Max Roach."

Drumming however, was to take a back seat in Prévost's musical output as AMM developed and began to acquire and enhance its innovative reputation. And, apart from rare musical outings he did not commit himself, more fully, to the jazz drum kit again until 2007/08. Although, continuing to play percussion, a jazz-inflected project with Seymour Wright and Ross Lambert in an ensemble called SUM was the precursor of a period more devoted to drumming. Apart from various ad hoc ensembles, this led to various recordings including a series a CDs entitled Meetings with Remarkable Saxophonists. At date this consists of four volumes featuring Evan Parker, John Butcher, Jason Yarde and Bertrand Denzler respectively.The London workshop

Over the years Prévost has conducted many improvised music workshops. However, as a result of a seminar he conducted at The Guelph Jazz Festival, Canada in 1999, Prévost began to formulate a framework for a workshop based upon a more thorough working of AMM principles and practice. He wrote:

"I had, of course, already had long previous experience of improvisation and experimental music mostly through my participation in AMM and working closely with the composers Cornelius Cardew and Christian Wolff. From this experience I had begun a working hypothesis in my book 'No Sound is Innocent'. However, there is always more to discover. On my long flight across the Atlantic, I intuited more could be found out. Not through introspective, if rational, thought alone but, through discovery or experimentation: praxis. It can, of course, be very discomforting to watch a proposition die in practise. No theory is worth its salt unless it is fully tested. The best ideas - this experience suggests - emerge through activity. Hence, the working premise of the improvisation workshop had to be based upon an emergent set of criteria constantly tested within the cauldron of experience.

In November 1999 I made it known that a free improvisation workshop would start weekly in a room at London's Community Music Centre, near London Bridge. Originally, under the auspices of the London Musicians' Collective, [...] these premises were found and minimal lines of communication to possible interested parties were opened. The first Friday evening (not thought to be an auspicious evening of the week because people 'went out' to have a good time) duly arrived. The room was available precisely because no one ever hired it on a Friday! I waited. Edwin Prévost, The First Concert: an Adaptive Appraisal of a Meta Music, (2011) p.115/6

Since then the workshop has continued weekly. It has a strong collegiate atmosphere. Those who participate are themselves formulating and refining a programme of enquiry and empathy. The working premise is one of 'searching for sounds' (Cardew). The emphasis is upon discovery and not on presentation. It is a place to risk failure and develop an open and continuing processive relationship with the materials at hand and other people. As hoped and anticipated, Prévost's continual presence is no longer required. In his occasional absences senior colleagues (in particular Seymour Wright and Ross Lambert) more than adequately move the project along. To date there have been over five hundred people who have attended the weekly workshop in London, representing over twenty different nationalities. This activity is further augmented by occasional forums for discussion and London's Cafe OTO programmes ensembles drawn from the London workshop every month. There have also been occasional extended periods of collective workshop musical experimentation. And, in 2010 there was a residential workshop held in Mwnci Studios on the Dolwillym Estate, west Wales. (see various other texts: including Philip Clark's Wire piece)] There are now workshops based upon this general premise functioning in Hungary, Greece, Slovenia, Japan, Brazil and Mexico. Mostly started by alumni of the original workshop in London.Intermediate and experimental compositions

Cardew's 'Treatise' etc. Cardew's introduction to AMM in 1966 owes something to his search for musicians to perform his (then unfinished)193 pages long graphic score, 'Treatise'. The AMM musicians (at the time Lou Gare, Eddie Prévost, Keith Rowe and Lawrence Sheaff) seemed perfect candidates to embrace this bold work of imagination. And, with others (including later AMM member John Tilbury) all participated in the premier performance at the Commonwealth Institute on 8 April 1966 (check year!). But the initial impact of Cardew's induction into AMM was to bring a halt to his compositional aspirations. However, over the years since, AMM has had a long relationship with particular indeterminate and experimental works particularly those of Cardew - especially after his death in 1983. Most prominently 'Treatise'. Other favourites were 'Solo with Accompaniment', 'Autumn '60', Schooltime Compositions' and the text piece Cardew wrote particularly for AMM, 'The Tiger's Mind.' These pieces (which for a long time had been neglected within 'new' musical schedules), and occasionally others by Christian Wolff and John Cage, were sometimes played in conjunction with an AMM improvisation. Some concert promoters were, it seems, more interested in these pieces being played than the principal musical output of AMM. Hence, Prévost's ambivalence about the inclusion of such material in concert programmes. The creative search for primary performance material was diverted, in such works, in keeping with the demands of the notation or compositional scheme. This inevitably prevented the musician from (to use Cardew's own words) "being at the heart of the experiment". (Cardew, 'Towards an Ethic of Improvisation; CC R p. 127).Matchless Recordings and Publishing

In 1979 Prévost began the recording imprint of Matchless Recordings and Publishing. Although there had been some interest by commercial labels to take on the new improvising music of the late 1960s onwards, it proved not to be satisfactory or long-lasting. Together with a number of similar initiatives, e.g. Incus Records in Britain and ICP (?) in the Netherlands, Prévost sought to take control of their own work. In the early years this was slow and painstaking work. Some years little was produced and few small sales accrued. Gradually however, Matchless recordings began to be the documenting and disseminating base for a developing body of work. Most of the AMM output is featured on Matchless and this has diversified (more so in recent years) to include other associated artists and ensembles.[see matchlessrecordings.com] In 1995, following the same principal for internal control over the output, production and dissemination of material, the publishing imprint Copula was inaugurated. The first publication was Prevost's No Sound is Innocent. Later followed by Minute Particulars in 2004. 2006 saw the publication of Cornelius Cardew: A Reader (edited by Prévost) which was a collection of Cardew's published writings accompanied by commentaries by a number of musicians associated and inspired by Cardew. This volume was an essential companion to John Tilbury's comprehensive biography Cornelius Cardew: a life unfinished which was also published by Copula in 2008. The most recent book to appear on this imprint is Prévost's The First Concert: An Adaptive Appraisal of a Meta Music (2011).

Eddie Prévost is the cousin of the ex-docker shop-steward and left-wing political activist also named Eddie Prevost."
