“Nijinsky’s version, it’s very beautiful,” Anne Teresa De Keersmaeker said in 2006, when she premiered her own version of Debussy’s The Afternoon of a Faun. “The dancers are the ones who really convinced me that we should dare to perform a different version that doesn’t deny the past.” De Keersmaeker’s dares and experiments are always worth seeing. The Paris Opera Ballet pairs Faune with Ravel’s opera The Spellbound Child, which has a libretto by Colette. —L.J.
