AMM are an important British free improvisation group, founded in London, England in 1965.
AMM have never been well-known to the general public, but have been, in their own way, influential. AMM have been called "legendary" and "groundbreaking.", and are notable as perhaps the first musical group deliberately to try to make music not related to any established musical genre: as Michael Nyman wrote, "AMM seem to have worked without the benefit or hindrance of any kind of prepared external discipline."
Most of their recordings have been released on Matchless Recordings, run by founder 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!"
