What about the fourth movement of Ginatstera's Sonata #1?
there's always the Barber Piano Concerto but there's already a dance piece called "Configurations" and Baryshnikov comissioned it when he was still the artistic director of ABT. there's a video of him dancing it, which is totally awesome. one of my ballet teachers liked to use Yanni's music which i didn't like but it's easy to set dances to.
