The Metropolitan Opera's production of Strauss' Der Rosenkavalier now looks a bit tired but the performance was anything but. All of the leads were in great form, giving performances that were detailed and moving or by turn funny. However, the evening belonged to Susan Graham whose Octavian, aside from being beautifully sung, was extraordinarily believable. The same could be said for the Ochs. Flemming was a lovely sensuous Marschallin but hers was not the last word on the subject. On occasion I missed the charm of, say, Elizabeth Schwartzkopf whose identification with the role lingers in the memory. Still, all around, this was a deeply moving account, made even better by the verve and vitality of Edo de Waart's conducting.
