Lamb was a San Francisco-based rock group who appeared at the famed Fillmore Auditorium several times in the early 70s. The band was formed by Texan singer Barbara Mauritz and guitarist Bob Swanson.

   Says Wikipedia: “Their debut album on the Fillmore label, A Sign of Change, was perhaps their most uncompromising and experimental, relying largely on jazz-folk acoustic arrangements and spotlighting Mauritz’s impressive voice on impressionistic, dream-like lyrics.”

   The album has been released on CD but is out of print. Be prepared to pay $40 and up.
