Performer: Twyla Tharp Dance Foundation

Despite my reservations about Diabelli, there is no doubt Twyla Tharp is one of the most inventive, adventurous voices in dance still (and she's 83). She deserves her flowers.

Two world premieres and a piece created in 1975. Tharp herself came onstage to raucous applause. She might be “pop dance”, but audiences love it.

Watching Twyla Tharp move now is a reminder of how much she has affected the landscape of dance during her lifetime.
