Randy Jackson Presents: America's Best Dance Crew Cast & Crew

Eight dance crews of five to seven members each go through strenuous rehearsals and arduous challenges in a bid to win a touring contract and cash prize. Former 'N Sync member JC Chasez and choreographer Shane Sparks provide feedback to the various crews, while viewers vote for their favorites online or via phone and text message. The two weakest teams as determined by the voting go into a "battle zone" to bust their best moves for the judges, who determine which team advances to the next round and which one is eliminated. Mario Lopez hosts. Randy Jackson, Rob Lee, Howard Schwartz, Karen Schwartz, Harriet Sternberg and Joel Gallen are executive producers.
