What opera house both housed the Paris National Opera and frequently featured Vasyl Slipak?
Opéra Bastille The Opéra Bastille (    ) (Bastille Opera House) is a modern opera house in Paris, France. Inaugurated in 1989 as part of President François Mitterrand’s “"Grands Travaux"”, it became the main facility of the Paris National Opera, France's principal opera company, alongside the older Palais Garnier; most opera performances are shown at the Bastille along with some ballet performances and symphony concerts, while "Garnier" presents a mix of opera and ballet performances.
Stoclet Palace The Stoclet Palace (French: "Palais Stoclet" , Dutch: "Stocletpaleis" ) is a mansion in Brussels, Belgium. It was built by architect Josef Hoffmann for banker and art lover Adolphe Stoclet between 1905 and 1911 and is located in the Sint-Pieters-Woluwe / Woluwe-Saint-Pierre area of Brussels. Considered Hoffman's masterpiece, the Stoclet's house is one of the most refined and luxurious private houses of the twentieth century. The sumptuous dining and music rooms of the Stoclet Palace exemplified the theatrical spaces of the Gesamtkunstwerk, celebrating sight, sound, and taste in a symphony of sensual harmonies that paralleled the operas of Richard Wagner, from whom the concept originated. In his designs for the Stoclet Palace, Hoffmann was particularly attuned to fashion and to the Viennese identity of the new style of interior, even designing a dress for Madame Stoclet so that she would not clash with her living room decor as she had while wearing a French Paul Poiret gown.
