david freiberg, a folk-guitarist friend of valenti's, was recruited to the group. he had previously been in a band with paul kantner and david crosby but like cipollina he had been arrested and briefly jailed for marijuana possession and had just been released. "we were to take care of this guy freiberg," cipollina recalled, and though they had never met before, freiberg was integrated into the group. the band also added skip spence on guitar and began to rehearse at marty balin's club, the matrix. balin, in search of a drummer for the band he was organizing (which became jefferson airplane), convinced spence to switch instruments and groups.
