Vienna State Opera
The opera house was the first major building on the Vienna Ringstrasse commissioned by the Viennese "city expansion fund". Work commenced on the house in 1861 and was completed in 1869, following plans drawn up by architects August Sicard von Sicardsburg and Eduard van der Nüll. It was built in the Neo-Renaissance style by the renowned Czech architect and contractor Josef Hlávka.
Vienna Chamber Orchestra
The WKO was founded in 1946, and its first artistic directors were Franz Litschauer, Heinrich Hollreiser, Paul Angerer, and Carlo Zecchi. When he took over the position from 1976 to 1991, Philippe Entremont started a tradition of conductors playing a dual rôle, appearing as both conductor and soloist. Entremont has continued as the Orchestra's lifetime honorary conductor, leading it on tour and in its matinée subscription series at the Konzerthaus. In addition, the WKO has continued to invite dual-role artists, including Yehudi Menuhin, Heinz Holliger, Heinrich Schiff, and Ola Rudner.
