BoomBox is an electronic act that plays an organic mix of blues and house music with an ear to rhythm and dance music. Founder Zion Rock Godchaux — the son of Grateful Dead singer Donna Godchaux — writes the tunes and sets the scene and has done so for nearly 20 years. Tonight his group plays Humbrews at 9 p.m. ($20). Expect the glorious sounds that one might muster from the FM radio waves from decades past filtered through an interstellar breakbeat engine.
