Though they draw inspiration from garage rock, girl-group pop, and other signs of the baby boom’s teenage revolution, Shannon and the Clams boast a vitality that keeps their music from getting stuck in 1964. On the Oakland trio’s third album, singer/bassist Shannon Shaw and singer/guitarist Cody Blanchard further refine their efforts at musical time-traveling with results that range from the punchy “Bed Rock” to “Ozma,” a candy-colored ballad that would be perfect for sock hops should they ever get the revival they deserve.
