Bootie SF takes over all FOUR ROOMS at DNA Lounge to bring you our annual monster mashup spooktacular! We've got a Midnight Costume Contest, where we're giving away $200 First Prizes (and a trick-or-treat goody bag) for each of the best costumes in three categories: Best Overall, Best Group, and Scariest, plus Lobsterdust (NYC), Adrian A, and Tyme throwing down spooktacular mashes to keep you on the dance floor until well past the witching hour. Upstairs there's three more rooms filled with hauntingly good dance tunes, plus a special spooky set from Smash-Up Derby at 11:11 PM, and $7 cocktails before 10 PM.

Launched in San Francisco in 2003, Bootie Mashup throws the biggest and best all-mashup dance parties in the world, mixing and matching pop songs both past and present. With its theme parties and clever mashup formula, Bootie Mashup has been an unstoppable juggernaut for nearly 15 years, winning numerous nightlife awards in multiple cities. Keeping your brain guessing and body dancing with creative song combinations, it's the soundtrack for the A.D.D. generation.
