With the New Year comes new opportunities to delight in masterworks like George Balanchine's timeless Serenade and La Valse and his two-act comedic story ballet Harlequinade. The season also includes Jerome Robbins's The Goldberg Variations and The Cage, a premiere by resident choreographer Justin Peck set to Aaron Copeland's Rodeo, last season's Pictures at an Exhibition by Alexei Ratmansky and the return of ballet master-in-chief Peter Martins's Romeo + Juliet. And for the third season, the company hosts its art series, in which it commissions an artist to create works inspired by its dancers. This season features Brooklyn's Dustin Yellin, whose glass sculptures of multidimensional human forms will be on view in the theater. All tickets to art series performances (Feb 12, 19 and 27) are $29, and audience members take home a commemorative, original artwork by Yellin.
