When Bolin left after the band's second release Going Back to Colorado, he was replaced by Jock Bartley, and the band recorded the album Sunset Ride, their second for Warner Brothers Records. On Sunset Ride, Candy Givens displayed her gifts as a singer, composer, and harmonica player. The album was produced by David Givens, who wrote most of the songs. As a result of his stint with Zephyr, Bartley went on to a successful career with Gram Parsons and Firefall. Drummer Michael Wooten went on to play for several years with Carole King and was a founding member of the jam band Leftover Salmon. Various versions of Zephyr continued to play in Colorado until Candy Givens died of a drug and alcohol overdose in Boulder on 27 January 1984 at the age of 37. The release of "Heartbeat" in 1982 was promoted with a music video that incorporated early examples of computer animation combined with live action.
