The world-renowned SF Symphony is set to put on one of the most festive parties of the year as 2011 turns into 2012. Get out your gowns and tuxes, slick back that hair, and put on your dancing shoes. They'll bring the masks, champagne and, of course, the world-class music.

All you have to do is show up ready to party. Begin the evening at 8 pm with jams from the Martini Brothers in the lobby. After the concert, enjoy complimentary prosecco and desserts, relive the 80s with venerable cover-band-about-town Tainted Love on the First Tier, or to the Peter Mintun Orchestra on the stage of Davies Symphony Hall. Get your tickets here before they all sell out!
