Not much ballet but it does have in July
Nutcracker (Lesley Collier and Dowell)
Swan Lake (Yuri Makhalina etc)
It also broadcast excerpts from the Kirov Classics DVD - (Chopiniana, Petruska etc)
They did broadcast La Bayadere a few months ago.
I think it is great for opera lovers more then ballet goers. I was about to fork out £25 for Queen of Spades - only to find out that it was on this channel next month
