Sound Exchange might not have the widest selection of local music ? the place is too small for that ? but it's still the best spot to buy the stuff. That's because the staff there knows local music like no other salespeople anywhere, and they pretty much stock anything from any band willing to walk in with a consignment. And Sound Ex is where most local rock musicians shop, too, so there's a decent chance you can get your CD autographed while you're there. And on occasion, the store hosts raucous, BYOB in-stores, most often starring local punk, indie rock and metal bands.
