Seattle's best 18-plus dance night has been killing it too hard to stay a monthly event. So, starting tonight, Club Pop goes fortnightly. To celebrate, they're bringing in NYC genre-masher Drop the Lime and Atlanta electro BAPE-ster Le Castle Vania. Resident DJs Colby B and Glitterpants will warm things up. The beats will be hot, the crowd will be hotter, and Club Pop will be kicking your ass twice as often from now on. (Chop Suey, 1325 E Madison St, 324-8000. 9 pm, $10, 18+.)
