Time to resurrect Firebird thanks to the current Diaghilev-Fokine triple bill at the Kennedy Center (January 2012)! It's been a while since we discussed various versions here, in the context of seeing the current Kirov-Mariinsky version, which dates to 1994, when the choreographer's grand-daughter, Isabel, and Andris Liepa, staged this and Scheherazade on the company, reviving the original stage settings (somewhat abridged).
I mentioned this elsewhere, but I do find Nina Ananiashvili's Firebird interpretation from the Liepa staging to be the best I've come across. In fact, all the Mariinsky soloists have taken to mimicking her performance in the latest productions of The Firebird. Kondaurova is closest in feel, but she's not the actor that Ananiashvili was.
