Polica features members from Vampire Hands, Gayngs, and Bon Iver. Their hybrid of hip-hop, techno, and new wave indie sounds is addictive. You've heard the band lots on 88.9. If you were lucky, you saw them in January at The Cactus Club. A double-drummer set-up shakes the ground while frontwoman Channy Leaneagh makes your hairs stand on end.
