Their first release in 2000 performing Cornelius Cardew's "Treatise", for 20 years the Formanex quartet of sound artists, conceptualists and experimenters Anthony Taillard, Christophe Havard, Emmanuel Leduc, and Julien Ottavi are heard here in collaborations with Keith Rowe, Kasper T.

The full two-hour performance of Cornelius Cardew's entire 193-page legendary Treatise graphic score, performed at Iklectik in London, England on January 28, 2017 in an 11-member ensemble of some of London's most interesting improvisers including participants in Scratch Orchestra, in a double CD release with liner notes by AMM founder Eddie Prevost.

A collection of Feldman compositions primarily for piano as recorded by his earliest interpreters: Cornelius Cardew, John Tilbury, David Tutor, Cantilene Chamber Players, and Feldman himself.

Perhaps the most iconic and "classic" of AMM albums, recorded at The Crypt in London in 1968 with AMM as the quartet of Cornelius Cardew on piano & cello, Lou Gare on saxophone and violin, Christopher Hobbs on percussion, Eddie Prevost on percussion, and Keith Rowe on guitar & electronics.
