The sugarplums are tucked away for another year; the dancers took a breather. Now the New York City Ballet can get back to its real job, preserving the masterworks of founder George Balanchine. Five shows in this six-week winter season, including tonight’s opener, focus on his enduring classics Serenade, Agon, and Symphony in C; ten other programs offer more Balanchine. Embracing Valentine’s Day are eight performances of Peter Martins’s Romeo + Juliet, with Per Kirkeby’s ominous designs; completing the schedule are dances by Jerome Robbins and Christopher Wheeldon, and new works by Alexei Ratmansky (to Mussorgsky) and Justin Peck (to Aaron
Copland’s iconic score for Rodeo).
