Performing in New York for the first time since the former American Ballet Theater principal dancer Angel Corella was named artistic director, Pennsylvania Ballet arrives with three local premieres. Trey McIntyre's "The Accidental" is a four-part response to songs by Patrick Watson; Matthew Neenan's "Keep" features 10 performers meditating on love and relationships; and "Grace Action," Nicolo Fonte's first work for the company, puts a dozen dancers at the mercy of Philip Glass.
