Sean Carnage has been blowing minds and eardrums with his weekly music-and-mayhem nights at Pehrspace for three years now, so it's time to mark the big anniversary with a party. Tonight's overstuffed bill features loud, wicked, yet strangely danceable punk-rock tunes from bands hailing from LA and elsewhere. The music goes off amid the Rewarding Savagery with Sweets, a collection of Zaq Landsberg's disturbingly funny depictions of sentient piñatas protecting themselves from far-reaching sticks of destruction.
