Los Angeles

The second-annual edition of this DJ battle (which boasts an all-night open bar from Belvedere and Amp) pits different event promoter/lifestyle brands playlists against each other, tournament style; whomever's tunes move the dance floor more moves to the next round, with the winner taking home a year of bragging rights. Participants include the record company Stones Throw, the streetwear boutique Barracuda, and the ubiquitous promoter/blogger behind EatSkeet, a term you just recently learned grosses you out.
