Richard Strauss’s Der Rosenkavalier waltzes into HGO in a stylish production that transports audiences into the 18th-century comedy of manners into the chic world of 1950s Vienna, where the glamorous Marschallin is having an affair with the young Count Octavian—until his heart is captured by Sophie, the innocent fiancée of the blundering Baron Ochs. What follows is a delicious mix of mistaken identities, romantic awakenings, and bittersweet partings, all set to Strauss’s lush, sparkling score, filled with swirling waltzes and opera’s most transcendent final trio.
