We have two acts from two different Verdi operas, presented in their entirety on the Met’s then current sets, and then an abbreviated second act from Strauss’ Die Fledermaus, the act where a party scene often turns into a sort of gala. And so it does here, at much extended length. At least all the guests are on stage, and the Prince Orlofsky, Anne Sofie Von Otter, introduces each one in character (which brings its own tedium before long, unfortunately). Performance date: October 24, 1991.
