Blending indie rock, pop, and electronica, Spirit of the Bear utilizes two keyboard players, bringing a unique depth to their sound. The band's new single “Wires” features crooning vocals and mellow synths but still has enough edge to qualify as indie rock. A new album comes out in July. Expect to hear songs from it when the band plays tonight at 7:30 at House of Blues Cambridge Room. Tickets cost $15.
