If you’re in Philadelphia this weekend, there’s one party happening that trumps any ordinary night out. For its third year DJ Tritton’s Zombie Butt Touch is moving from the underground warehouse to a major venue: the 941 Theatre. Tritton’s own team of make-up artists will zombify every party-goer willing to rock like the dead. Dance to a dozen DJs spinning everything from dubstep to psytrance. Notable acts include Native State’s KiloWatts and lyricist Amagine for a project called Super Galactic Expansive. This is one of those parties that will set the tone for the rest of the summer. Let’s go nuts.
