New York City Ballet
The following is the current artistic staff (except dancers, who are listed at List of New York City Ballet dancers):The 66-member NYCB Orchestra is an important symphonic institution in its own right, having played for virtually all of the thousands of performances NYCB has given over the decades. It is one of the most versatile orchestras in the world, on any given week performing perhaps three or four times the repertoire that another symphony might be expected to do. Principal players of the orchestra also perform the majority of the concertos, other solos, and chamber music in the NYCB repertory as well. The orchestra accompanies the ballet on all of its North American tours, and while the ballet uses local orchestras on its international tours, members of the NYCB Orchestra often go along as soloists or extras.
Pennsylvania Ballet
Under Kaiser’s leadership, the company has expanded its Balanchine-based repertoire to include new works from both established and emerging choreographers. New works have included premieres of original ballets from choreographers Merce Cunningham, Christopher d'Amboise, Trey McIntyre, Matthew Neenan, David Parsons, Val Caniparoli, Benjamin Millepied, and Christopher Wheeldon, as well as the highly acclaimed 40th anniversary commission of Swan Lake by Christopher Wheeldon and the 2007 world premiere of Matthew Neenan’s "Carmina Burana". Currently employing 37 dancers, Pennsylvania Ballet annually presents a season of six programs (including George Balanchine’s The Nutcracker™ ) that balance classic ballets with new works that challenge the dancers and attract a diverse audience. The company also tours throughout Pennsylvania and the East Coast to venues such as New York City Center and the John F. Kennedy Center for the Performing Arts. It made its international debut at the Edinburgh International Festival in August 2005.
