"John William Stevens (10 June 1940 in Brentford, Middlesex - 13 September 1994 in Ealing, west London) was an English drummer. He was one of the most significant figures in early free improvisation, and a founding member of the Spontaneous Music Ensemble (SME).

Stevens was born in Brentford, the son of a tap dancer. He used to listen to jazz as a child, but was initially more interested in drawing and painting (media through which he also expressed himself throughout his life). He studied at the Ealing Art College and then started work in a design studio, but left at 19 to join the Royal Air Force. He studied the drums at the Royal Air Force School of Music in Uxbridge, and while there met Trevor Watts and Paul Rutherford, two musicians who became close collaborators.

In the mid-1960s Stevens began to play in London jazz groups alongside musicians like Tubby Hayes and Ronnie Scott, and in 1965 he fronted a septet. Influenced by the free jazz he was hearing coming out of the United States by players like Ornette Coleman and Albert Ayler, his style began to move away from fairly traditional be-bop to something more experimental.

In 1966 SME was formed with Watts and Rutherford and the group moved into the Little Theatre Club at Garrick Yard, St. Martin's Lane, London to develop their new music. In 1967 their first album, Challenge, was released. Stevens then became interested in the music of Anton Webern, and the SME began to play generally very quiet music. Stevens also became interested in non-Western musics.

The SME went on to make a large number of records with an ever changing line-up and an ever changing number of members, but Stevens was always there, at the centre of the group's activity. He also played in a number of other groups, drumming in Watts' group Amalgam and later forming bands like Freebop and Fast Colour, for example, but the SME remained at the centre of his activities.

In the latter part of 1967 Evan Parker joined the SME and worked closely with Stevens in the group, eventually becoming one of the longest standing members. He later summed up Stevens' approach to improvising in two basic maxims: if you can't hear another musician, then you're too loud; and there is no point in group improvisation if what you are playing doesn't relate to what other members of the group are playing.

Stevens also devised a number of basic starting points for improvisation. These were not "compositions" as such, but rather a means of getting improvisational activity started, which could then go off in any direction. One of these was the so-called "Click Piece" which essentially asked for each player to repeatedly play a note as short as possible.

Stevens played alongside a large number of prominent free improvisors in the SME, including Derek Bailey, Peter Kowald, Julie Tippetts and Robert Calvert, but from the mid-1970s, the make-up of the SME began to settle down to a regular group of Stevens, Nigel Coombes playing violin, and Roger Smith playing guitar. During the mid-1970s Stevens played regularly with guitarist and songwriter John Martyn as part of a trio that included bassist Danny Thompson. This line up can be heard on Martyn's 1976 recording Live at Leeds.

From 1983 Stevens was involved with Community Music (CM), an organisation through which he took his form of music making to youth clubs, mental health institutions and other unusual places. Notes taken during these sessions were later turned into a book for the Open University called Search and Reflect (1985). In the late 70s and early 80s John was a regular performer at the Bracknell Jazz Festival.

Aside from SME, Stevens also ran or helped to organise groups that were more jazz or jazz-rock based, such as Splinters, the John Stevens Dance Orchestra, Away, Freebop, Folkus, Fast Colour, PRS, and the John Stevens Quintet and Quartet. He also contributed significantly to Trevor Watts' group Amalgam and Frode Gjerstad's Detail, as well as collaborating with Bobby Bradford on several occasions.

The SME continued to play, the last time being in 1994 with a group including John Butcher. Stevens died later that year."

"Kenneth Vincent John Wheeler, OC (14 January 1930 - 18 September 2014) was a Canadian composer and trumpet and flugelhorn player, based in the U.K. from the 1950s onwards.

Most of his performances were rooted in jazz, but he was also active in free improvisation and occasionally contributed to rock music recordings. Wheeler wrote over one hundred compositions and was a skilled arranger for small groups and large ensembles.

Wheeler was the patron of the Royal Academy Junior Jazz course.

Wheeler was born in Toronto, Ontario, on 14 January 1930. Growing up in Toronto, he began playing cornet at age 12, and became interested in jazz in his mid-teens. Wheeler spent a year studying composition at the Royal Conservatory in Toronto in 1950. In 1952 he moved to Britain. He found his way into the London jazz scene of the time, playing in groups led by Tommy Whittle, Tubby Hayes, and Ronnie Scott.

In the late 1950s, he was a member of Buddy Featherstonhaugh's quintet together with Bobby Wellins. Throughout the sixties, he worked with John Dankworth, and also formed part of (Eric Burdon and) the Animals' Big Band that made its only public appearance at the 5th Annual British Jazz & Blues Festival in Richmond (1965) with tenors Stan Robinson, Dick Morrissey and Al Gay, baritone sax Paul Carroll, and fellow trumpets Ian Carr and Greg Brown. In 1968, Wheeler appeared on guitarist Terry Smith's first solo album, Fall Out.

Wheeler performed and recorded his own compositions with large jazz ensembles throughout his career, beginning with the first album under his own name, Windmill Tilter (1969), recorded with the John Dankworth band. A CD was released by BGO Records in September 2010. The big band album Song for Someone (1973) fused Wheeler's characteristic orchestral writing with passages of free improvisation provided by musicians such as Evan Parker and Derek Bailey, and was also named Album of the Year by Melody Maker magazine in 1975. It has subsequently been reissued on CD by Parker's Psi label.

In the mid-1960s, Wheeler became a close participant in the nascent free improvisation movement in London, playing with John Stevens Parker, the Spontaneous Music Ensemble and the Globe Unity Orchestra. Despite the above-noted accomplishments, much of his reputation rests on his work with smaller jazz groups. Wheeler's first small group recordings to gain significant critical attention were Gnu High (1975) and Deer Wan (1977), both for the ECM label (Gnu High is one of the few albums to feature Keith Jarrett as a sideman since his tenure with Charles Lloyd). One exception from the ongoing collaboration with ECM was his rare album on CBC called Ensemble Fusionaire in 1976. This had three other Canadian musicians and was recorded in St. Mary's Church in Toronto for a different character to the sound than on the ECM recordings.

Wheeler was the trumpet player in the Anthony Braxton Quartet from 1971 to 1976, and from 1977 he was also a member of the chamber jazz group Azimuth (with John Taylor and Norma Winstone).Later life

In 1997 Wheeler received widespread critical praise for his album Angel Song, which featured an unusual "drummerless" quartet of Bill Frisell (guitar), Dave Holland (bass) and Lee Konitz (alto sax).

Wheeler died after a short period of frail health at a nursing home in London on 18 September 2014. He was 84 years old."

"Paul William Rutherford (29 February 1940 - 5 August 2007) was an English free improvising trombonist. Born in Greenwich, South East London, Rutherford initially played saxophone but switched to trombone. During the 1960s, he taught at the Guildhall School of Music and Drama.

In 1970, Rutherford, guitarist Derek Bailey and bassist Barry Guy formed the improvising group Iskra 1903, which lasted until 1973. The formation was documented on a double album from Incus, later reissued with much bonus material on the 3-CD set Chapter One (Emanem, 2000). A film soundtrack was separately released as Buzz Soundtrack. Iskra 1903 was one of the earliest free improvising groups to omit a drummer/percussionist, permitting the players to explore a range of textures and dynamics which set it apart from such other contemporary improvising ensembles as SME and AMM. The group's unusual name is the Russian word for "spark"; it was the title of the Iskra revolutionary newspaper edited by Lenin. The "1903" designation means "20th century music for trio"; occasionally Evan Parker played with the group (Iskra 1904) and Rutherford also at one point assembled a 12-piece ensemble called, inevitably, Iskra 1912. The group was later revived with Philipp Wachsmann replacing Bailey, a phase of the group's life that lasted from roughly 1977 to 1995; its earlier work is documented on Chapter Two (Emanem, 2006) and its final recordings were issued on Maya (Iskra 1903) and Emanem (Frankfurt 1991).

Rutherford also played with Globe Unity Orchestra, London Jazz Composer's Orchestra, Centipede, the Mike Westbrook Orchestra, and the Orckestra, a merger of avant-rock group Henry Cow, the Mike Westbrook Brass Band and folk singer Frankie Armstrong. He also played a very small number of gigs with Soft Machine. He is perhaps most famous for solo trombone improvisations. His album The Gentle Harm of the Bourgeoisie is a landmark recording in solo trombone and his 1983 Trio album Gheim, recorded at the Bracknell Jazz Festival is another acclaimed work.

Rutherford died of cirrhosis of the liver and a ruptured aorta on 5 August 2007, aged 67."

"Trevor Charles Watts (born 26 February 1939 in York) is an English jazz and free-improvising alto and soprano saxophonist. He is largely self-taught, having taken up the cornet at age 12 then switched to saxophone at 18. While stationed in Germany with the RAF (1958-63), he encountered the drummer John Stevens and trombonist Paul Rutherford. After being demobbed he returned to London. In 1965 he and Stevens formed the Spontaneous Music Ensemble, which became one of the crucibles of British free improvisation. Watts left the band to form his own group Amalgam in 1967, then returned to SME for another stretch that lasted until the mid-1970s. Another key association was with the bassist Barry Guy and his London Jazz Composers' Orchestra, an association that lasted from the band's inception in the 1970s up to its (permanent?) disbandment in the mid-1990s.

Though he was initially strongly identified with the avant-garde, Watts is a versatile musician who has worked in everything from straight jazz contexts to rock and blues. His own projects have come increasingly to focus on blending jazz and African music, notably the Moiré Music ensemble which he has led since 1982 in configurations ranging from large ensembles featuring multiple drummers to more intimate trios. He has only occasionally recorded in freer modes in recent years, notably the CD 6 Dialogues, a duet album with Veryan Weston (the pianist in earlier editions of Moiré Music). A solo album, World Sonic, appeared on Hi4Head Records in 2005.

Watts has toured the world over numerous times, run workshops, received grants and commissions, and he has collaborated with some of the great jazz musicians including Archie Shepp, Steve Lacy, Don Cherry and Jayne Cortez. As of 2011, he continues to travel and toured North American with Veryan Weston."
