“If you asked a New York ballet dancer to name the teacher of the moment, Azari Plisetski would probably not spring to mind. But Mikhail Baryshnikov would like to change that. A major admirer of Mr. Plisetski, 69, who is widely credited with rejuvenating Cuban ballet in the 1960’s and bringing Cuban male dancers to the fore internationally, Mr. Baryshnikov invited Mr. Plisetski to teach professional classes this week at his [Manhattan] studios.”
