I just noticed an interesting page on PNB's new website. It lists all the ballets PNB considers to be in the active rep with the date the ballet was first performed. Worth a look!

I am sad to see that "Mozartiana" is not on the list, although the last time I saw it was in the mid-90's, if I remember correctly, with Anne Derieux.

The PNB premiere date is a big help, but I wish that either it was searchable, or that it was organized by choreographer rather than alpha order by title (whine, whine, whine...)

I agree about Mozartiana, but I was very surprised to see that Dark Elegies and Jardin aux Lilas were listed -- it's been ages since they were performed.

(now how about a "last performed" date category...)
