If we're lucky, someone in Jackson will post the info from the programs, because I can't find anything specific on the site.
The Round II compulsory contemporary piece had to be chosen from specific pieces made available by Matthew Neenan and Trey McIntyre on video, and then the competitors had the chance to work with the choreographers on site. The contemporary piece for the Finals (Round III) had to be choreographed after 2010 and be a maximum of four minutes:
I don't know if he commissioned a piece -- he'd have a lot of options just from his colleagues -- got permission to use something PNB presented, or got permission to do another existing contemporary work. "Emergence" is too old, and I doubt the solo in silence in the recent Morris would count. The only extended solo I remember in the Cerrudo is for a woman.
There's nothing I can find that specifies the version of the variations for the classical rep Columns A&B. The only ballets he'd have seen at PNB are the Stowell male variation for "Nutcracker" and the Hynd and reconstructed versions of the "Sleeping Beauty" male variation, both in Column A. I don't know if there's anything else he would have danced as a PD, but it would be sweet were he to dance to a reconstructed version working with Doug Fullington. I know Doug's worked on "Raymonda," (also Column A), "La Bayadere," and "Le Corsaire," but Ali wasn't added until 1955; so much for Medora and the Slave.
