The Csardas Princess

The Volksoper Wien’s first-rate production of “Die Csárdásfürstin” (“The Csárdás Princess”) offers a rare chance to waltz through one of operetta’s most tuneful hits. Emmerich Kálmán’s score, to a libretto by Béla Jenbach, is a frothy concoction of romance, hedonism, and too much time spent in nightclubs.
