Master Class, a play by Terrence McNally at the Samuel J. Friedman Theatre, Manhattan Theatre Club. This brilliant play by the opera loving Terrence McNally has its third Broadway performance, and the best so far from the great Tyne Daly. Daly doesn't remotely resemble Callas, she is neither lithe, nor tall, but from the first time she walks on, she's in command, of the audience, and of the role. It is a remarkable performance from this versatile actress who is superlative in everything she does. As the students, Sierra Boggess, the original Little Mermaid, is lovely and sings difficult music quite well. Alexandra Silber who was a marvelous Julie Jordan in a London Carousel at the Savoy, is terrific as the flummoxed soprano. Garrett Sorenson displays a fine tenor voice in a Tosca selection. But it is of course Daly who is the show here. I don't know how effective this play would be for an audience member who is not versed in opera lore, but for those who are, this is a great ride.
