The National Youth Dance Company hunts out talented teenagers from all over England. Their latest performance will premiere at Sadler's Wells on Friday. Judith Burns went to one of their rehearsals."This is the centre point. We have worked on this. Remember this. Don't dance off the stage. You are all intelligent beings," shouts rehearsal director Niku Chaudhari.
The largest rehearsal studio at Sadler's Wells theatre in north London is roughly the size of a tennis court.
Days before they premiere on the Sadler's Wells stage, the dancers fill the space, moving together in what Niku says should be "an organised mess".
There's encouragement as well as criticism: "It looks cool, it really does," she tells them.
