Zephyr was a blues-based hard rock band formed in 1969 in Boulder, Colorado by guitarist Tommy Bolin, keyboardist John Faris, David Givens on bass guitar, Robbie Chamberlin on drums and Candy Givens on vocals. Although the charismatic performances by Candy Givens were originally the focal point for the band, it was the flashy guitar work of Tommy Bolin that the band is best remembered for. After Bolin left, he was replaced by Jock Bartley, and the band recorded the album Sunset Ride, their second for Warner Brothers Records. The album is still in print and is much loved by a small but loyal following. On Sunset Ride, Candy Givens displayed her gifts as a singer, composer, and harmonica player. The album was produced by David Givens who also authored the majority of the tunes. As a result of his stint with Zephyr, Bartley went on to a successful career with Gram Parsons and Firefall and drummer, Michael Wooten, went on to play for several years with Carole King. Various versions of Zephyr continued to play in Colorado until Candy's death in 1984. The release of "Heartbeat" in 1982 was promoted by a video that incorporated very early examples of analog computer animation combined with live action.
