退廃芸術
In addition to operas like "Lohengrin", "Così fan tutte", "Der Rosenkavalier" and "Aida", several dramaturgical "leitmotifs" were to be found in the programming of the "Opernwunder" years of the Bruns era. A number of operas from the "Entartete Kunst" (Degenerate art) period were performed for the first time since being banned by the Nazis in the 1930s. Publishers and opera house staff recreated lost orchestral materials for productions of Bohuslav Martinů's "Julietta", Karoly Rathaus' "Fremde Erde", and Ernst Toch's "Der Fächer". German romantic operas that had been lost since the 19th century were given new life, thus the rediscovery of Robert Schumann's "Genoveva", Louis Spohr's "Faust" and Carl Maria von Weber's "Die drei Pintos" for the operatic stage. Some operas from abroad received their European premieres in Bielefeld, such as John Adams' "Nixon in China" and Shulamit Ran's "Der Dybbuk". The Bielefeld Opera also produced a number of world premieres, including Nikolai Karetnikov's "Till Eulenspiegel" and 's "Das stille Zimmer".
