Big Tune, a beat competition that started two years ago at the War Room, returns home after touring a galaxy of cities. Emerging producers present their beats to the people, the old-school way, and the people judge the boom and the bap. The beat that rocks the crowd the most is the beat that wins. As Jonathan Moore says, "The speakers don't lie." (The War Room, 722 E Pike St, 328-7666. 9 pm, free, 21+.)
