It won’t be easy to find tickets, but it is worth a try… One of the most popular operettas of all time, Johann Strauss’s «Die Fledermaus,» opened at the Olympia Theater last Friday. It is an older production by the Greek National Opera, a favorite with Athenian audiences, which meets with great success every time it is staged – and will run for a limited number of performances until the end of April. Strauss composed the operetta in just six weeks, in 1874. The well-known musical farce is set in Vienna, at a time when champagne and the waltz reigned. The sweet dance music makes it hard to remain seated and the comic prose causes endless laughter. Directed by Spyros Evangelatos, the operetta is alternatively conducted by Liza Xanthopoulou and Vladimiros Symeonidis. The sets and costumes are by Giorgos Ziakas and the choir is conducted by Fani Palamidi. The choreography is by Angelos Hadzis. Zachos Terzakis and Thanos Petrakis alternate in the role of Gabriel von Eisenstein, Jenny Drivala and Maria Kokka in that of Rosalinda, while interpreters also include Gina Poulou, Vassiliki Karayianni, Syranous Tsalikian, Giorgos Stafetas, Haris Andrianos, Costas Mavrogenis, Stamatis Beris and Nikos Stefanou. The remaining performances have been scheduled for tonight, Friday to Sunday and April 16, 19, 21 and 23. The Olympia Theater is situated at 59 Academias, tel 210.361.2461, 210.364.3725.
