As a kind of primer for the Paul Taylor Dance Company's performances later this season, its training ensemble Taylor 2 performs company standards like Company B and Profiles in a show with modern dance iconoclast Molissa Fenley. And to celebrate the 50th anniversary of New York City Ballet, former principal dancers Merrill Ashley and Peter Martins, now the company's director, offer Balanchine anecdotes and discuss the history of the company and of ballet at "Words on Dance," which features film clips of the pair dancing singly and as partners. NYCB will stage work by Balanchine (Agon), Robbins (The Concert), and Martins (Fearful Symmetries), the successor to that formidable choreographic legacy.
