Celebrate Halloween early with dripping blood and paint when the “always live” art and music throwdown Artslam! focuses on all things undead. Big Soy, Las Hijas de La Chingada, the Hawks of Holy Rosary, and Snowbyrd provide the death-rattling soundtrack for more than 20 flesh-eating visual artists caught in the gruesome act of creation. As if that’s not enough to make your ears fall right off your rotting skull, DJs JJ Lopez and Scuba spin hot, oozing vinyl until every last brain has been eaten. $5, doors at 9pm, the White Rabbit, 2410 N St Mary’s, (210) 737-2221, artslamsa.com.
