Balletomane. For mobile users: my gifs are here (and my tags for them are here).
There’s something so dramatic about this that I love, though I’m not really a Balanchine choreography fan.
Dancer is Bart Cook in First Variation: Melancholic.
Awesome gif! Bart Cook and his wife (Maria Calegari, former Principal Ballerina for NYCB) are my ballet teachers!!
