With piles of albums clogging the counter and posters, t-shirts and cardboard cutouts sprinkled throughout the shop, the Disc Exchange is as much a visual trip as an audio one. A throwback to the days when indie record shops ruled,this south St. Pete storefeatures rare classics and new release CDs, cassettes and DVDs. But it's the good old-fashioned vinyl records that keep collectors and nostalgia buffs coming back for more. Products can also be ordered through the store's Web site.
