Tonight, Club Pop throws its last bash, celebrating three and a half years of doing the damn-near impossible: throwing an (actually cool) 18+ dance night in a city where it's practically illegal to go out dancing if you're under 21. (Okay, it is technically legal, but can be prohibitively expensive for promoters—extra security staff and all that.) The night goes out with its signature conflagration of rock and dance, featuring local upstart trio the Tempers and L.A. DJ Paparazzi. Where are kids supposed to go in this town now? I don't know. (Chop Suey, 1325 E Madison St, 324-8000. 9 pm, $8 before 11 pm/$10 after, 18+.)
