Hold off on that New Year's diet and detox, my friends. There's one more party you can't miss, and it's being hosted by the funnest punk band that ever was, the Spits. I know we've already spilled a lot of ink on these dudes, but you haven't seen a live show until you've seen THEM. Their audiences lose their collective minds. You'll happily walk away with some bruises, or maybe even a souvenir black eye. You should also walk away with their new album, Kill the Kool—a compilation of tour-only rarities. Sex Crime and Wimps open. (Chop Suey, 1325 E Madison St, 9 pm, $8 adv/$10 DOS, 21+)
