Watch R. Strauss: Der Rosenkavalier (Salzburger Festspiele) (2014) : Online Full Movies With their “comedy for music” in the spirit of Mozart, Richard Strauss and his inspired librettist Hugo von Hofmannsthal created the most popular of all their works and one of the most frequently performed operas of all time. In the guise of a gossamer-light and supremely entertaining high-class comedy, Der Rosenkavalier touches on universal themes such as love, sex, marital fidelity and the changes that human relations undergo over time – and all of it set to music of the most glorious kind imaginable. With its stellar cast under the inspired direction of Harry Kupfer, the 2014 Salzburg Festival’s production of Der Rosenkavalier was one of the most internationally acclaimed interpretations of the work since the start of the new millennium. “A musical feast from beginning to end“ (Wiener Zeitung).
