This fixture in the starving-music-nut scene has grown to six local outlets, but the Lake Street location has it running away for sheer selection. Sure, the walls are lined with posters of unmentionable Euro-acts and the floor is in drastic need of recarpeting, but they have more titles than the New York Islanders. Not only do they offer thousands of albums you were sure had been lost to the ages, from the Screaming Blue Messiahs' Gun Shy to techno legend Jeff Mills's Live at the Liquid Lounge, they'll pay generously for discs you were sure the ages had absolutely zero use for. Tired of those Supertramp discs? Need gas money? Try Cheapo.
