"Andrew Ball studied with Kendall Taylor at the Royal College of Music and took a First in music at Queen's College, Oxford. Regarded as one of the foremost British pianists of his generation, a busy career has taken him all over the world. He has a reputation for innovative and imaginative programmes, and chamber music and contemporary music have always played a large part in his repertoire. He has given countless premieres (including the first British performance of Sofia Gubaidulina's Piano Sonata at the Bath Festival), made his Proms debut playing Messiaen and studied Tippett's sonatas with the composer. Ives and Busoni are also special interests.

He has played with the Nash Ensemble, London Sinfonietta, Villiers Piano Quartet and Gemini and has had a successful duo with Madeleine Mitchell since 1992. Many acclaimed CDs range from the complete Tippett song-cycles and vocal and choral music of Lili Boulanger with Martyn Hill for Hyperion, to Billy Mayerl's works for piano and orchestra. He has appeared at the Aldeburgh Festival playing two-piano music with Rolf Hind and has played in Stravinsky's 'Les Noces' for the Royal Ballet at Covent Garden and with the LSO and Gergiev at the Barbican.

Formerly a sought-after teacher at the Guildhall School of Music and Drama, Andrew Ball was Head of Keyboard at the Royal College of Music from 1999 to 2005, where he remains a Professor. He was made a Fellow in 2006. He regularly gives masterclasses, including Berlin, Singapore, Malaysia and Japan."

"Paul Dunmall was born 1953, Welling, Kent; saxophones, clarinets, bagpipes, miscellaneous wind instruments.

As told to Watson (1989), Paul Dunmall was a working class lad from Welling who left school at 15 and spent two years repairing instruments at Bill Lewington's shop in Shaftesbury Avenue, London. He turned professional at 17 and, following two years touring Europe with a progressive rock band (Marsupilami), joined the Divine Light Mission, a spiritual movement led by Guru Maharaj Ji and moved from London to an ashram in America. He told Isham (1997), 'I moved to an ashram full of musicians - a music ashram - but it was still spiritual practice. That gave me a spiritual understanding through meditation, Coltrane's music, and all the rest of it, led me to that, and that's been a fundament in my life ever since - that I can actually sit down and meditate and forget my body. I realise how important meditation is in my life... but I don't do it so much these days.' During the three years he lived in America, Dunmall played with Alice Coltrane (in a big band with the Divine Light Mission) and toured for twelve months with Johnny 'Guitar' Watson.

Back in England, he played with Danny Thompson and John Stevens as well as folk musicians Kevin Dempsey, Martin Jenkins and Polly Bolton and then, in 1979 he became a founder member of Spirit Level (Tim Richards, piano; Paul Anstey, bass; Tony Orrell, drums), staying with the group until 1989. During his time with Spirit Level, Dunmall joined the two-tenor front line group Tenor Tonic with Alan Skidmore (1985), played and broadcast with Dave Alexander and Tony Moore in the DAM trio (1986) and formed the Paul Dunmall Quartet with Alex Maguire, Tony Moore and Steve Noble (1986).

In 1987 Paul Dunmall joined the London Jazz Composers Orchestra, being a constant member and appearing on all their recorded output from that date onward. The following year the improvising collective quartet Mujician was formed by Keith Tippett, Dunmall, Paul Rogers and Tony Levin and has continued to be a regular performing, touring and recording group, sometimes augmented by other musicians. Dunmall has also played in a trio with Keith and Julie Tippetts and in Keith Tippett's big band Tapestry. Two other duos have also sprung out of Mujician: Dunmall with Tony Levin (two CD releases) and Dunmall in folk-influenced outings with Paul Rogers. Another regular playing partner throughout this period and up until the present includes Elton Dean.

In 1995, two trios were formed, the first with Oren Marshall, tuba and Steve Noble, percussion, the second with John Adams, guitar and Mark Sanders, percussion, these sometimes coming together as a quintet. More recently, Dunmall has played in another reeds/guitar/drums trio with Philip Gibbs and Tony Marsh and there appears to be regular crossover between all these players. The Paul Dunmall Octet was founded in 1997."

Dunmall also has released a large number of albums and a box set on the UK FMR label, in various configurations and instrumentation.

"Hilary Jeffreys was born in 1971 in Surbiton, England, works as a musician and is currently based in Berlin. His musical career started with a journey to the Sahara Desert in 1990 and the sense of silent space which he experienced there is a sustaining influence on his work. He took a degree in music at Dartington College of Arts and the University of York between 1990 and 1993. Early contact with UK jazz musicians such as Paul Dunmall and Keith Tippett have had a lasting influence on Hilary's approach to music. After completing his studies he became a freelance musician. His early engagements include a tour of UK, Scandinavia, Europe and North America with an Anthroposophic theatre company called Portal Productions for a new version of Rudolf Steiner's fourth mystery play "The Soul's Awakening". After completing this tour Hilary settled in London, worked as a session musician and taught music to theatre students at Queen Mary and Westfield College and Central School of Speech and Drama. During this time he also worked on many compositions including solo pieces for trombone and for the Slovakian cello player Jozef Lupták.

In 1998 he moved to Arnhem, Netherlands to study music composition for dance and trombone with the American composer-trombonist James Fulkerson. After completing this year of study Hilary continued his freelance work in UK and Netherlands, moving between Arnhem, London, York, Oxford, The Hague and Birmingham. During this time he also took classes in electronic music at the Institute of Sonology in The Hague, recorded several albums, toured throughout Europe and played twice in Tokyo for a dance production by the Japanese choreographer Saburo Teshigawara. In 2002 he settled in Amsterdam and became part of the music scene there, performing in many clubs and theatres as well as curating his own club nights and organising funded projects including a research project at Steim. A lot of Hilary's music at this time focused on improvisation and jazz, included work with the saxophonist Tobias Delius and the formation of several ad-hoc ensembles. A European tour with the Jimi Tenor Big Band in 2003 kicked off an active touring life, with recording sessions, theatre / dance shows and composition commissions in between life on the road!

In 2007 he was invited to join the ensemble zeitkratzer, based in Berlin. This invitation, combined with many other contacts with the thriving music scene there resulted in a move to Berlin in 2011. In 2013 Hilary started to study Dhrupad with Amelia Cuni, aiming to apply techniques of this Indian classical music tradition to the trombone, they also recorded and performed together as Tonaliens with Werner Durand and Robin Hayward. Since moving to Berlin Hilary has also played at most of the major stages and festivals in the city including Berghain, Club Transmediale, Haus der Kulturen der Welt, HAU, Jazzfest, März Musik, Hamburger Bahnhof, Silent Green and Volksbühne. Berlin based ensembles with whom he currently works include Zinc & Copper, Minor Tom, Tonaliens, Mullet and Mouse On Mars Dimensional People Ensemble.

Hilary travels widely, performing in major international stages and festivals worldwide. He has received composition commissions for Slagwerk Den Haag, GRM Acousmonium, David Kweksilber Big Band, Apa Ini and his ensemble Minor Tom. He has been invited for artistic residences such as Recollets in Paris (2012), won the Henriette Bosmans Prize for his composition "Vishnu Stockings" (Netherlands, 2009) and appears in many different recordings on various labels including Aquarellist, Bocian, Col Legno, Comatonse, Edition Telemark, Fat Cat, Faux Amis, Fourth Dimension Records, FMR, Dilemma, Important Records, Mikroton, New World Records, Philophon, Shhpuma, Silent Records, Soul Jazz, Sloow Tapes, Sub Rosa, Subtext, Zeitkratzer Records and Karl Records."
