Breakonomics

-- Forget freakonomics--check out breakonomics at MIT. These breakdancing battles include three-on-three breakin' and one-on-one poppin' and house. We're not entirely sure what that means, but all forms of breakdancing are awesome, so we're in regardless. Nemesis, Toys, and Popsicle are among the judges. La Sala de Puerto Rico (MIT Student Center 2nd Floor), 77 Massachusetts Ave, Cambridge, 12pm-6pm. $3 MIT, $7 student, $12 others. (KS)

Style and More

-- Legends of Style throws a mean party with cool threads, hot beats (from Kon and Amir, DJ Knife, and DJ Rugged One), and cold drinks, all combining to give you a wicked good time. Boston Center for the Arts, 539 Tremont St, 7:00pm. 21+, $15 advance, $20 doors. (KS)

Dirty Proms
