Although formed in Davis, CA, Kak were based in San Francisco for a good part of 1968, when they recorded their only album. Lead singer, guitarist, and primary songwriter Gary Lee Yoder and lead guitarist Dehner Patten had been in the Oxford Circle, an obscure early Northern Californian psychedelic band that had cut one garage/psych single ("Foolish Woman"/"Mind Destruction") and played some shows on the San Francisco psychedelic circuit, while bassist Joe Dave Damrell had been on a 1965 single on Scorpio Records with Group "B".
