It's a record store by day, but the employees lose their High Fidelity music-snob attitudes and reveal themselves as the scene boosters they really are by night, when they open up the old house to live music after retail hours. From death metal to free jazz, Sound Exchange hosts performances that are always mind-expanding, far beyond the mainstream and that can't be found anywhere else in the city. Or, as they put it in their own words, "Presenting unlistenable music to an uncaring public for 25 years. Does your band make people run from the room? Book a show with us." (BYOB)
