On December 28, Angela Brower makes her greatly awaited Metropolitan Opera debut as Octavian in Robert Carsen’s splendid staging of Der Rosenkavalier, with Sir Simon Rattle on the podium to conduct Strauss’s glittering score and Katie Van Kooten as the worldly Marschallin. Günther Groissböck returns with his definitive take on the lascivious Baron Ochs, and Golda Schultz sings the innocent Sophie.
