An excellent DVD of the Royal Ballet performing Dances at a Gathering has just been released. The coupling is especially interesting too. See here http://www.musicweb-international.com/classrev/2021/Apr/Cellist-dances-OABD7277D.htmMany of the good ones can't be found on YouTube in high quality video. But you can find segments of Jerome Robbins' "Dancers at a Gathering" here.
The ballet consists of a number of dances set to the solo piano works of Chopin.
