The centrally located Unheard Of, which owner Nick Accurso likens to an “upscale Deveroes,” advertises itself as a “street pusher of rare goods.” The shop offers an array of cool, limited-run T-shirts, watches, sunglasses, hats and, of course, shoes in a high-end boutique environment. Unheard Of celebrates its first anniversary on Saturday. Accurso has rented out a warehouse space right next door to the store for a massive, all-ages dance party. (A $10 bottomless cup is an option if you’re over 21 and want to get your drink on.) It starts at 9 p.m.
