“Underground” is a relative term. One could argue that all the ‘60s San Francisco psychedelic bands were underground, because the music they made was so far removed from the pop and rock sounds that came before them. But of all the bands in the scene, Lamb was perhaps the most underground of them all. It wasn’t just that their blend of rock, folk, classical, country, blues, and gospel was as hard to classify as any of the era. It was also their vibe. Along with classically trained guitarist and songwriting partner Bob Swanson, Barbara Mauritz’s versatile vocals paced material often imbued with a haunting, mystical aura. Yet they could also be earthy and rootsy, occasionally drifting into spacey psychedelia with hints of raga-rock. Released in the early ‘70s, Lamb’s first two albums, A Sign of Change and Cross Between, did indeed offer some of the most intriguing and eclectic music of any San Francisco rock band on the psychedelic scene. But Lamb’s history predated the release of those records by a good couple of years or so. So prolific were Mauritz and Swanson that quite a few of their original compositions didn’t make it onto their albums, though these were often on par with the songs that did find official release. Unlike many bands of the time who had a bounty of surplus quality tunes, Lamb often taped these in studios and studio-like rehearsal conditions, as well as making some professional tapes of their live performances. Fortunately, many of those tapes survive, including a good number of songs that didn’t find a place on their LPs, as well as substantially different versions of some that did. The best of these from the late 1960s find release for the first time on An Extension of Now: Unreleased Recordings 1968-1969. This collection not only rounds out our picture of one of San Francisco rock’s finest underappreciated acts, but also serves as a first-class document of Lamb as they made their transition from a more standard rock outfit to a group not easily comparable to any other in the region, or indeed any other anywhere. Our black vinyl and CD (with extra tracks, limited to 500) releases feature liner notes by Richie Unterberger drawn from an interview with Bob Swanson, who has also contributed photos and memorabilia from his private archive. Produced by noted Bay Area archivist Alec Palao…if you’re a fan of late-‘60s S.F. psych, you have to hear this!
