The sixth annual Expansions MLK dance party is spun by Masa, SunTzu Sound, and the everloving Reverend Dr. DJ Riz, who describes the event thusly: "In the past, it's been a smile love fest, not just an evening of DJs wanking over drunks, but as close to a house party in a club as these things get. The beats will be all over the map, three DJs going from dub to drum and bass and a smidgen of hiphop. I'm feeling Curtis Mayfield these days... and we always toss in the speeches. Sounds corny, and yet it always works on this night." If you can't be there, listen to the simultaneous broadcast on KEXP. (Neumos, 925 E Pike St, 709-9467. 8 pm, $5, 21+.)
