The enormously influential and talented Odetta was a fixture at Rainbow Sign. Bosom buddy of Mary Ann Pollar, she could be counted on to perform regularly, blessing audiences with her powerful voice and lightning-fast fingerpicking. At this event in 1975, Odetta shared a billing with The Liberian Tribal Dancers, a visiting company of 25 dancers, singers and musicians. This was a benefit for Rainbow Sign but was not held at Rainbow Sign. Instead, the concert went up at Berkeley Community Theater, a much larger venue.
