AMM - AMMusic 1966
Originally recorded and released in 1966, this has long been considered one of the early high-watermarks of contemporary improvised music/sound. AMM were one of the first completely non-idiomatic free improvising ensembles, and this was their very first release, which was truly startling for 1966, & is still pretty damn revelatory over 35 years later! Out of print for over 20 years, this includes 30 minutes of bonus material from the original sessions. This really was decades ahead of its time. With Cornelius Cardew, Lou Gare, Eddie Prevost and Keith Rowe.
