The return to San Francisco comes after a successful tour in the east coast. Acts like B. B. King and Albert King would open for the band during the tour. This album has lengthier renditions of their associated songs including "Light Is Faster Than Sound" extending over 7 minutes. Overall, the recordings are just another instance of the band's growing interest.
Live at Winterland '68 includes many tracks from Cheap Thrills, the band's breakthrough studio album. "Ball and Chain" is the only track from Cheap Thrills recorded live and it is a live rendition from one of these 1968 shows at the Winterland Ballroom.
