Opera and ballet are really outside of my field of knowledge.
I love Carmen, and I like Madama Butterfly, La Boheme, and Pagliacci. That is just about the extent of my opera experience and knowledge.
I don’t care much for Nutcracker (which I guess somehow makes me anti-Christmas), but I enjoy Sleeping Beauty, and Swan Lake. I used to love the works of the Joffrey Ballet, in particular The Green Table, and one that was called Olympics or The Olympics (or something like that).
