Two parties. One night. Both perfect for you and your dilated pupils. First up, we have Go Bang! at Deco Lounge in the Tenderloin. The regular club night snorts things into high gear with a most festive end-of-2011 bash. But don't take our word for it. Hell no. Here's what SF Bay Guardian's delicious Marke B had to say about Go Bang!: "This awesome, mixed-crowd monthly disco party has zero attitude but all the glamour. It's like a Studio 54 you can actually get into. Atlanta's DJ Osmose will bring his scratching turntable technique to bear on some rare disco tracks this NYE, along with Doc Sleep, Eddie House, and hosts Sergio and Steve Fabus. Good times!"

Go Bang!: 9 p.m.-blackout, Deco Lounge (510 Larkin), $10, don't be a drunk asshole.

Our second selection is the big fat party going on at Public Works, the Sunset and Honey Soundsystem party. Promising "quality music without the drama," the night will boast aural pleasure from DJs Solar, J-Bird and Galen from Sunset, and DJs Jason Kendig, Kenvulsion, Robot Justle, Derek Bobus and P-Play from Honey Soundsystem. Someone named KiNK will also man the decks for the swooning masses on the dance floor. Delightful.

Sunset and Honey Soundsystem: 9 p.m.-5 a.m., Public Works (160 Erie), $20-$25, don't puke in the sinks.
