You might need to hear him drop his stuttering "s-s-s-Say Wuuut" signature into a track before you recognize one of his songs in a DJ mix, but if you've been listening to contemporary club music at all in the past three or four years, you already know his sound: rubbery synth horns, hammering drums, and a fuller, more aggressive mix than the somewhat thin, spacey minimalism that's plagued too much recent, post-breakbeat Baltimore club. And between his DJ album Crank It! and the Unruly Records digital EPs Beats Extraordinaire and It's Go Time, Say Wut just keeps on churning out new tracks, with increasingly inventive variations on that sound, fortunately more often without the constant Lil Jon samples that used to be one of his less welcome trademarks.
