(S04E06) The first night of performances and we've got a lot to consider. Nigel and Mary were joined by hip-hop choreographer Dan Karaty at the judges table and they led us through ten couples. We saw everything from smooth waltz to Broadway. And only one thing is for certain: it's going to be a tough competition. As Dan said in the beginning of the show, there are no front runners.

But after the ten couples strutted their stuff, the pack of ten had some leaders. Find out what happened last night on So You Think You Can Dance after the jump.
