Ever hear Radiohead's "Idioteque" blended into Cybotron's "Techno City"? Probably not. That's a typical Tim Sweeney move. One of DFA boss James Murphy's favorite DJs, Sweeney possesses the specialized knowledge and keen mixing sense that get hips thinking and brains dancing. His Beats in Space radio program/podcast on WNYU airs the cream of cosmic disco, techno, Kraut rock, freak folk, house, rock, and other genres, making unexpected, brilliant transitions his trademark. With Rong Music head Ben Cook and H.M.A. (Chop Suey, 1325 E Madison St, 324-8000. 9 pm, $10, 21+.)
