Last month, the Peach Pit '90s dance party made the big move to DC9 from Dahlak (via a two-month pitstop at Liv). Professional sound system! Multiple bars! Rooftop deck! Talk about a step up, eh? If you want to shake your groove thing to the Soup Dragons, Pet Shop Boys, Deee-Lite and other pop favorites, swing by Ninth Street after 10 p.m.
