Although Elephant Revival's multi-instrumentalists all contribute to its Celtic-inspired harmonies, its the beautifully morose vocals of Bonnie Paine that best represents the band's jammy jazz sound. The group utilizes diverse instrumentation, from the washboard and fiddle to the upright bass to create this folky fusion -- coming across solidly as the quintet are true pros, having worked with everyone from Michael Franti to Railroad Earth. This show is 21 and up, tickets are $15, and doors open at 7 p.m.
