Southern California’s Nails play an abrasive brand of crust-fueled hardcore beyond the boundaries of traditional metal. On last year’s Abandon All Life, the band packs so much sheer violence into the 17-minute punch-out of a record that anything longer would have you begging for mercy. Gluttons for punishment, be prepared. With Iron Lung, Bone Sickness, Skinfather, Gag. El Corazon. 7:30 p.m. $10 adv. All ages. JB
