AMM is a British free improvisation group that was founded in London, England, in 1965. The group was initially composed of Keith Rowe on guitar, Lou Gare on saxophone and Eddie Prévost on drums. The three men shared a common interest in exploring music beyond the boundaries of conventional jazz, as part of a larger movement that helped spawn European free jazz and free improvisation. AMM have never been well known to the general public, but have been influential on the field of improvised music. Most of their recordings have been released on Matchless Recordings, which was run by founding member and percussionist Eddie Prévost. In a 2001 interview, founding member Keith Rowe was asked if "AMM" was an abbreviation; he replied, "The letters AMM stand for something, but as you probably know it's a secret!"
