This scarce document appeared on Derek Bailey's Incus label in 1972 and remains highly regarded as a milestone in British improvised and avant-garde music. The pioneering experimental group is captured live at the legendary Roundhouse -- the London venue that hosted "swinging London" happenings (early Pink Floyd and Soft Machine made their names on the stage in the abandoned train station). While remaining obscure but influential, it is rumored that during this period AMM had fans in Syd Barrett, Paul McCartney, and John Lennon, who related to the group's abstract sound art and free improvisation. The AMM approach stemmed from a hybrid of post-John Cage concepts in sound liberation and the free jazz of Cecil Taylor and Ornette Coleman. Much later in the group's progression, the members of AMM came to be understood as the forefathers who forged some of the earliest experiments in noise music. This recording is an extremely rare LP that contains of the more abstract noise recordings of their career, with the reduced lineup of Eddie Prevost on drums and Lou Gare on saxophone -- the sound is no less challenging than their work with the extraordinary "prepared" guitarist Keith Rowe.
