“Michelle Dorrance is a new kind of tapper. Classically, tap is a matter of a cool, contained upper body suspended over a huge clatter down below—a contrast that is supposed to be witty and, in a great or even good tapper, is. (“My feet are producing twenty taps a second, in alternating rhythms? Gee, I didn’t notice.”) Dorrance supplies plenty of action in the feet, but meanwhile the rest of the body is all over the place. Her elbows fly out; so do her knees, in great, lay-an-egg squats. She looks like a happy little tomboy vaulting around in a tree. Now and then, she’ll put on the mood-indigo, darkness-in-my-soul expression sometimes seen in tappers, or, alternatively, the Vegas-y let-me-entertain-you expression, but both of them fall off her face pretty fast, because she is fundamentally unaffected.”
