A New Justin Peck Work for New York City Ballet Justin Peck, who at 25 is one of the youngest choreographers ever commissioned by the New York City Ballet, is creating a new ballet for the company's annual "New Combinations Evening" on Jan. 31, the company announced. Mr. Peck's world premiere, set to "Sinfonietta LaJolla" by the Czech composer Bohuslav Martinu, will replace a previously announced world premiere by the company's ballet master in chief, Peter Martins. Mr. Martins's ballet, with a commissioned score by Marc-Andre Dalbavie, has been postponed until the company's 2014 winter season to allow Mr. Dalbavie more time to complete the music. The company's "New Combinations Evening" honors George Balanchine's legacy by presenting world premiere ballets on or around the anniversary of his birthday, Jan. 22. Mr. Balanchine died in 1983. In addition to Mr. Peck's work, the evening will include Alexei Ratmansky's "Concerto DSCH" and Mr. Balanchine's rarely performed "Variations Pour une Porte et un Soupir." The new work by Mr. Peck, who also dances with the company, is his third premiere for City Ballet. His first piece for the company, "In Creases," was set to "Four Movements for Two Pianos" by Philip Glass. It had its premiere in July during the company's annual summer season at the Saratoga Performing Arts Center. "In Creases" will have its New York City premiere on May 29. Mr. Peck's second commission, "Year of the Rabbit," had its debut in October during City Ballet's fall season. All performances are at the David H. Koch Theater, at Lincoln Center.
