Harnoncourt: Johann Strauss: Die Fledermaus At the Wiener Festwochen in May 1999, Nikolaus Harnoncourt conducted for the first time one of the most sparkling and comical of German Operas, the Fledermaus. Fast and vivacious as the mood of the opera is, Harnoncourt's interpretation is slower and reflective. From its rehearsal to its actual Premiere, we witness the unfolding of a new philosophy. ORCHESTRA: Wiener Symphoniker CONDUCTOR: Nikolaus Harnoncourt PERFORMERS: Wolfgang Brendel, Silvana Dussmann, Agnes Baltsa, Edna Prochnic, Anton Scharinger, Herbert Lippert, Olaf Bär, Arnold Schönberg Choir
