Record stores have enough financial issues as it is, but try making it work when you only sell one genre. To be fair, UGHH.com—founded back in 1997 by a Northeastern business student—started on the web, and earns 90 percent of its revenue via mail-order purchases. The store is less than ideal for browsers, with computer kiosks in place of traditional rows of physical albums, but UGHH's rap inventory remains peerless. it also carries T-shirts, watches, graffiti supplies and more. Buy enough, and they might throw in a free poster. UGHH also hosts free live performances—time things right, and you might catch a drop-in from a Wu-Tanger.
