District78 creates the master mixes used at America's Best Dance Crew callback auditions and on the shows. On their website, they've released the Kanye West 'Power' mix used at the ABDC 6 Chicago auditions, and promise to release each of the other three over the next weeks. The website also has a sweet collection they're calling America's Best Mixtape. And, on their JunHeeLee08 Youtube channel, they preview master mixes to be used this season including Cee-lo's 'Forget You', Sophia Fresh's 'This Instant', and MIMS' 'Making Money'. Thanks for the tips, Jai and Ninjaboi!
