Also outstanding were Carlo Bergonzi and Alfredo Kraus, skillfully making the most of resources depleted by old age; Ileana Cotrubas, "ripely and irresistibly nostalgic" in "Giuditta"; Plácido Domingo, combining "magnificent vocalizing and the most acute artistic intelligence" in "Don Carlo" and "Faust"; Renée Fleming, "luscious and immaculate" in "Louise", "Don Giovanni" and "Der Rosenkavalier"; Waltraud Meier, singing Isolde's curse with "thrilling ferocity"; and Ruth Ann Swenson, compensating for her technical deficiencies in a coloratura showpiece from "Roméo et Juliette" with character abd intelligence.
