This institution still has one of the best collections of dance music on vinyl in the Midwest. Find what moves you--from techno, hip-hop, UK or US hardhouse, trance, or disco classics--and spin it for yourself at one of their listening stations. The stock is 75 percent new and 25 percent used, with some quite rare. They also stock DJ gear, like slip mats for turntable scratching and big square bags to tote LPs from gig to gig.
