Bitches Brew is a studio double album by jazz musician Miles Davis, released in June of 1970 on Columbia Records. Recording sessions took place at Columbia's 30th Street Studio over the course of three days in August of 1969. The album continued Davis' experimentation of 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.
Often cited as one of Davis' best-selling albums and masterpieces, Bitches Brew marked a turning point in modern jazz. Upon release, it received mixed criticism from fans and critics, alike, due to the album's unconventional style and revolutionary sound. Later on, Bitches Brew gained recognition as one of jazz's greatest albums and a progenitor of the jazz rock genre, as well as a major influence on rock and funk musicians. In 1998, Columbia Records released The Complete Bitches Brew Sessions, a four-disc box set that included the original album as well as ensuing studio sessions through February 1970.
