Miles in the Sky is Miles Davis's first studio album to significantly incorporate electric instruments, marking a transition toward jazz fusion. Recorded at Columbia Studio B in New York, the album features Herbie Hancock on electric piano and Ron Carter on double bass, though electric bass was also used on some tracks.
The album was released in July 1968 and represents a bridge between the modal jazz of his earlier work and the more avant-garde style he would develop on In a Silent Way and Bitches Brew. The piece 'Stuff' stands out for its use of the Fender Rhodes electric piano, while 'Paraphernalia' features guitarist George Benson as a guest.
Although not as revolutionary as its immediate successors, Miles in the Sky was well received by critics and reached number 111 on the Billboard 200 chart. It is considered a key document of Davis's musical evolution toward fusing jazz with rock and funk.
