New feature on ABDC auditions - choreography callbacks

The Chicago Tribune reports on the America's Best Dance Crew Chicago auditions and profiles a auditioning tapdance crew called M.A.D.D. Rhythms. The article also mentions a new feature for the auditions: "About half of the 20 crews that auditioned Tuesday made the end-of-day "callback" round: a crash-course of new moves taught by an "ABDC" choreographer, to be incorporated on-the-spot into new routines."

I'm intrigued by the choreography callbacks and wonder what they bode for Season 4. And, I'm also intrigued by M.A.D.D. Rhythms; here's a 2009 performance from NoraClark721's Youtube Channel.
