Why do I love Emerald City Soul Club? Because ECSC is one night's blissful reprieve from the same old musical palette and constant THUMP THUMP THUMP of other club nights. Every 45 that the DJs play sounds familiar, even the ones I'm sure I don't know, and every song swings and spins and steps across a floor that's been sprinkled with baby powder for your dressed-up dancing pleasure. It's perfect. (Lo-Fi, 429 Eastlake Ave E, 254-2824. 9 pm, $7, 21+.)
