It's back. The quest for Red Bull Thre3Style's National Champion will begin in D.C. tomorrow night as the Rock N' Roll Hotel (1353 H St. NE) hosts the preliminary qualifying event. The DJ battle gives crowd-controllers 15 minutes and the task of satisfying the audience with three different genres of music. 

This year's event will feature DJ Trayze, DJ K-Meta, Mista Selecta, DJ Heat and last year's winner, Spinser Tracy. The competition will be hosted by Low Key of and guest judges include Yudu Gray, Jr., DJ Enferno and 2011 Northeast Thre3style champ GETLIVE!

The doors open and 9 p.m., the event starts at 10 p.m., and it's free as long as you RSVP here. A trip to the U.S. National Qualifier in L.A. and potentially the World Finals in Toronto are at stake, so expect to be blown away.
