Fans of the full-length classic ballet are in luck. New York City Ballet’s production by Peter Martins is at Lincoln Center’s Koch Theater February 19-March 2, and the Philadelphia Ballet’s version by Angel Corella is at Philadelphia’s Academy of Music March 6-16. Both productions take their cue from the original, choreographed in 1877 by Marius Petipa. Shown here is New York City Ballet principal dancer Sara Mearns, with dancers in the company.
