Johann Strauß’s »Die Fledermaus« from 1874 is a masterpiece of Viennese operetta: In order to take revenge on his friend Eisenstein, Dr. Falke (alias Die Fledermaus) stages a game of mistaken identities at Prince Orlofsky’s ball, where the guests include a Marquis and a Chevalier, a Hungarian countess and budding artists. However, nobody is who they claim to be. The masquerade and trickery end with the entire group of partygoers in prison. When the masks finally fall and extramarital shenanigans come to light, Falke’s revenge is complete. This production by Günter Krämer has been delighting Semperoper audiences since 2003 with classic numbers such as the Watch Duet, the Czárdás or Adele’s »Mein Herr Marquis« as well as the witty dialogue, updated with some amusing contemporary references. With diamond-sharp irony amidst the champagne glasses, »Die Fledermaus« is a great evening’s entertainment… and not just at the New Year!
