I regret that the liquor board is proposing new amendments to liquor licensing that would ban anyone under 21 from being in a live-music venue that also serves alcohol. Well tonight's all-ages show is the perfect backdrop for screaming a proverbial "fuck you!" to the proposed changes, with four stellar all-ages-supporting acts gracing the stage at an all-ages-supporting bar. So celebrate, dance, and pump your fists in the air in defiance of the fight to come. (El Corazón, 109 Eastlake Ave E, 381-3094. 7:30 pm, $12, all ages.)
