The revolutionary Bitches Brew was released on March 30th 1970. By that time Miles Davis had started performing in rock venues, bringing his music to a much broader audience. His remarkable band displays near telepathic interplay throughout the fiery, confrontational performance captured on this set, originally broadcast on KSAN-FM. Taking the form of one continuous piece, its a vital and exciting document of one of jazzs greatest innovators at his peak, and is presented here together with background notes and images.
