New York City Ballet
NYCB still has the largest repertoire by far of any American ballet company. It often stages 60 ballets or more in its winter and spring seasons at Lincoln Center each year, and 20 or more in its summer season in Saratoga Springs. City Ballet has performed "The Nutcracker", "Romeo and Juliet", "A Midsummer Night's Dream", and many more. City Ballet has trained and developed many great dancers since its formation. Many dancers with already developed reputations have also joined the ballet as principal dancers.
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.
