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.

A beautiful 3-CD set with a hardcover book presenting 3 full concerts from 2015 & 2016 of the AMM trio configuration of John Tilbury (piano), Keith Rowe (guitar) and Eddie Prevost (percussion). The 70 page book, dedicated to saxophonist Lou Gare, includes an AMM discography, plus photos, and essays by Paige Mitchell and Allen Fisher; Keith Rowe; Eddie Prevost; and Seymour Wright.

The dual alto saxophones of Martin Kuchen and Seymour Wright meet guitarist Keith Rowe for an impressive journey of free improvisation with Rowe taking the lead.
