Red Bull Thre3Style is a DJ competition where DJs are judged on track selection, creativity, mixing skills, stage presence, and crowd reaction. Each DJ gets one 15-minute performance where he or she will have to play a minimum of three genres. Anything goes: from house anthems to old-school hip-hop to Top 40 remixes. The event is hosted by Elizabeth Mendez, and features Michael Mogill, Four Color Zack, and CL's own Chad Radford as judges. Atlanta's winner will go on to compete in the South East Regional final on Feb. 22.
