It looks fascinating. Never seen Pina Bausch's take on the ballet.
In a not completely unrelated tangent, I miss being able to go to the Nicholas Roerich Museum on the Upper West Side to see work by the original scenic designer of the ballet.
Extended excerpts of her The Rite of Spring are featured in the excellent Wim Wenders documentary "Pina"--even more amazing if you can view it in 3D (the dances in this film are among my favorite uses of 3D ever)(available from Criterion Collection).
