Bitches Brew, Mati Klarwein, 1970
(The following info came from Wikipedia so NYPD might have fucked with it.)
Bitches Brew is a studio double album by jazz musician Miles Davis, released in April 1970 on Columbia Records. The album continued his experimentation with electric instruments previously featured on his critically acclaimed In a Silent Way album. With the use of these instruments, such as the electric piano and guitar, Davis rejected traditional jazz rhythms in favor of a looser, rock-influenced improvisational style.
