The band was formed in Davis, California, in late 1967, by singer, songwriter and rhythm guitarist Gary Lee Yoder, and lead guitarist Dehner Patten. Both had previously been members of The Oxford Circle, a garage rock and early psychedelic band. Adding Joe Dave Damrell on bass and sitar, and Chris Lockheed on drums and harpsichord, they started performing together as Kak around San Francisco. After meeting songwriter and record producer Gary Grelecki, they were signed by Epic Records. Richie Unterberger, "Kak", Allmusic.
