Swizz Beatz x America’s Best Dance Crew. Swizz Beatz and MTV’s “America’s Best Dance Crew” are collaborating on a pretty unique promo that is sure to give Swizzy some mainstream publicity outside of anything to do with Alicia Keys. The producer will be working with this season’s two final crews by creating the original music for the “Last Chance Challenge,” the contestants’ last chance to impress judges JC Chasez, Lil Mama and Omarion. Swizz will be prominently featured in the episode which airs later tonight.
