"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."
