It’s a night for dress-up much like Ann Rice’s infamous Vampire Ball. Well, maybe not that dark. DJs Hans 242 and Nblackoasis tag team four different decks for pure pleasure with dark retro, EBM, and industrial grooves. Naughty playroom featuring texSWITCH and free giveaways from Metropolis Records. No cover if you dress up — you know you want to. Free, 9pm, Wax Lounge, 2211 San Pedro, (210) 737-9191, myspace.com/waxclublounge.
