But this is a vintage production deserving attention on its own merits. As a matter of survival, veteran singers learn how to make experience compensate for the loss of youth, and Freni and Pavarotti are outstanding examples of how this can be done. They are aided by a sensitive stage director, a visual treatment responsive to the opera's changing moods, and an expert supporting cast deeply involved with the story and the music. They fit convincingly in roles with which they have been living for decades; both are still in good vocal condition, and the emotions are convincingly conveyed. In the supporting cast, note the excellent performances of Gino Quilico and Nicolai Ghiaurov. --Joe McLellan
