Watching a DJ isn't very stimulating. Most turntablists are better heard than seen -- unless they're topless, that is, looking out at you with a porn-vixen pout and pinching their nipples, as Portia Surreal is apt to do. An erotic fetishist from New York City, Surreal knows exactly how to turn her audience on. The techno gamine's hot breaks and strong, sultry beats leave dance-floor denizens sweaty, smiling and begging for more. Her sets incorporate recognizable grooves along with more obscure cuts, delving into tribal sounds as well as lighter electronica fare for a mix as sharp as her whip. Surreal gets her freak on this Saturday, April 10, at the Church, where porn luminaries Ron Jeremy and Tiffany Holliday will host Sexxxtravaganza. With DJ Rectangle also on the bill, the triple-X fest promises to be an aural orgy. You coming?
