I can’t wait to see what Alexei Ratmansky does with Stravinsky’s “Firebird,” premiering tonight during ABT’s national tour. I keep thinking of the way Dumbledore’s blood-red phoenix bursts into flames — how fantastic is the mixture of avian hauteur with exploding flame. I’m also thinking of an amazing recreation of “Firebird”‘s intensity at the Diaghilev show at the V&A Museum in London in 2010. The exhibition snaked along, a display of photos, paper artifacts and ornate costumes hanging heavily, worn boots set alongside. In the way back recesses of the room, one turned a corner to be violently immersed in the Fokine/Ballet Russe’s version of “The Firebird.” The two-story Goncharova city backdrop — thick with spires and domes — filled the space, Stravinsky blared at top volume, scarlet lights burned down. There may have been a small B&W film of the ballet, or some photos being projected on the wall — I can’t remember, I was so floored by the music and lights and the setting. It’s such an enveloping score, how it builds and thrashes and soars. The dance is built right in.
