The Peter Brötzmann Octet

Allmusic wrote about The Peter Brötzmann Octet's single album (Machine Gun), "This historic free jazz album is a heavy-impact sonic assault so aggressive it still knocks listeners back on their heels decades later. Recorded in May 1968, Machine Gun captures some top European improvisers at the beginning of their influential careers. Originally self-released by Peter Brötzmann, the album eventually came out on the FMP label, and set a new high-water mark for free jazz and "energy music" that few have approached since.
