Bitches Brew is a studio album by Miles Davis, originally released in 1970. It marked his continuing experimentation with electric instruments such as the electric piano and guitar in order to reject traditional jazz rhythms.
On his aptly titled 1973 solo debut, Spectrum, Billy Cobham revealed his interest and aptitude for the rock, jazz and funk genres. Spectrum reached No. 1 on the jazz charts around the world and became a crossover phenomenon.
