Umberto Giordano's opera Siberia with it's libretto by Puccini's successful librettist Luigi Illica (La bohème, Tosca) premiered in 1903 at La Scala as a replacement of Puccini's Madama Butterfly, which was not finished at the time. Madama Butterfly came out in Milan shortly after Siberia and flopped completely. Umberto Giordano, however, briefly became a public favorite. Shortly after successful re-runs on important theatres, including Buenos Aires, New York and São Paulo, Siberia could not maintain it's position in repertoire although Gabriel Fauré designated the second act as "one of the most remarkable and captivating that modern dramatic music can offer." This opera rarity performed at Bregenz Festival "is musical narrative theatre in perfection" (Süddeutsche Zeitung) in which "Uryupin leads the agile Wiener Symphoniker through the score with a sense for delicately tinted colours. Ambur Braid sings the challenging part of Stephanas with bravour" (Frankfurter Allgemeine Zeitung).
