Spirit was an American jazz/hard rock/progressive rock/psychedelic band founded in 1967, based in Los Angeles, California.
The original lineup of the group evolved from an earlier Los Angeles band, The Red Roosters, which included Randy California (guitars, vocals), Mark Andes (bass) and Jay Ferguson (vocals, percussion). With the addition of California's stepfather Ed Cassidy (drums), and keyboard player John Locke the new band was originally named the Spirits Rebellious (after a book by Khalil Gibran) but was soon shortened simply to Spirit. Randy California had also played with Jimi Hendrix (then known as Jimmy James) in Jimmy James and the Blue Flames in 1966.

His earlier career was primarily in jazz and included stints with Cannonball Adderley, Gerry Mulligan, Roland Kirk, Thelonious Monk and Lee Konitz. He was a founding member of Rising Sons with Taj Mahal and Ry Cooder.
The group's first album, Spirit, was released in 1968. "Mechanical World" was released as a single (it lists
