The Met assembled an ideal cast for François Girard’s acclaimed new production of Wagner’s final masterpiece: Jonas Kaufmann in the title role of the fool “made wise by compassion”, René Pape as Gurnemanz, the veteran Knight of the Grail, Katarina Dalayman as Kundry, Peter Mattei is Amfortas, the anguished ruler of the Grail’s kingdom, and Evgeny Nikitin sings the evil magician Klingsor.
