Giving it both barrels

In Joseph Roth’s The Radetzky March, the ageing Emperor Franz Joseph regrets the drab field-grey that has replaced his army’s once-colourful uniforms, seeing in it a premonition of an empire — a world — soon to be defeated and broken up. Franz Joseph is present in Act One of Robert Carsen’s new production of Der Rosenkavalier, right there in the Marschallin’s boudoir: I counted at least four portraits of the old man, gazing phlegmatically down on the sexually charged capers below. And the men in grey are there too. In Carsen’s conception, Baron Ochs and his yobbish retinue are cavalry officers, plotting on one side of the room, while on the other gorgeously dressed fashion models resembling drawings by Erté parade and pose. It’s 1911, the year of the opera’s première, and we all know — as Richard Strauss and his co-creator Hugo von Hofmannsthal did not — what happens next.
