Legacy of Return to Forever

Relayer is the seventh studio album by the English progressive rock band Yes, released in the UK on 29 November 1974 and in the US on 5 December 1974 by Atlantic Records. After keyboardist Rick Wakeman left the group in May 1974 over disagreements with the band's direction following their double concept album Tales from Topographic Oceans (1973), Yes entered rehearsals as a four-piece in Buckinghamshire. They auditioned several musicians, including Greek keyboardist and composer Vangelis, before settling with Swiss musician Patrick Moraz of Refugee who incorporated elements of funk and jazz fusion to the album. Relayer is formed of three tracks, with "The Gates of Delirium" on side one and "Sound Chaser" and "To Be Over" on side two. This was the only studio release to feature Moraz on keyboards.

The Headhunters is an American jazz fusion band formed by Herbie Hancock in 1973. The group fused jazz, funk, and rock music.

The Mahavishnu Orchestra was a jazz fusion band formed in New York City in 1971, led by English guitarist John McLaughlin. The group underwent several line-up changes throughout its history across its two periods of activity, from 1971 to 1976 and from 1984 to 1987. With its first line-up consisting of McLaughlin, drummer Billy Cobham, keyboardist Jan Hammer, violinist Jerry Goodman and bassist Rick Laird, the band received acclaim for its complex, intense music consisting of a blend of Indian classical music, jazz, and psychedelic rock as well as its dynamic live performances between 1971 and 1973. Many members of the band have gone on to acclaimed careers of their own in the jazz and jazz fusion genres.
