DJ Tracy Young won't be spinning Sunday at the Grammy's or at any Grammy after-party. She's also not nominated for a Grammy as a remixer -- and one of these days she better be! But who needs the Grammys? Young gets by with high-profile gigs for Madonna, MTV and others, and then there's her position as one of the most popular DJs on the gay circuit. Her sweet tribal sound is never cloying nor desultory. It's always tasteful and tuneful and celebratory. Widely appealing too: It's hard to imagine, for example, any dancehead not grooving to one of last year's better compilations, Young's light and hard Dance Culture 2. Tonight, Feb. 9, she returns to the Hippo in Baltimore, which is almost like a homecoming for the Miami-based D.C. native. Why not make it a parade and float on up I-95 for the occasion?....
