Friday night was a fantastic night at the Metropolitan Opera. Why? On the stage was Puccini's superb triple bill, "Il Trittico." It appeared in a splendid new production by Jack O'Brien. In the cast, or casts, were some of our best singers, and most of them were in top form. James Levine was in the pit, and he, too, was in top form — which is some form. And the Met orchestra played sensationally well.
