Die Zauberflöte production that Wilhelm Furtwängler had prepared with the painter Oskar Kokoschka for the Felsenreitschule was taken over by Georg Solti. Werner Egk’s Irische Legende (“Irish Legend”) received its world premiere under the baton of George Szell, while Rudolf Kempe gave Salzburg its first hearing of Pfitzner’s Palestrina. The ballet of the Vienna State Opera presented four evenings devoted to contemporary scores: Stravinsky’s Perséphone and Honegger’s La Danse des Morts. Behind the scenes a battle raged for the successor to Furtwängler, who had dominated the Festival in its recent years. A duel soon emerged between Böhm and Karajan. Official negotiations with Karajan began in the autumn. Karajan raised far-reaching demands, wishing not only to function as a conductor but as a stage director. He also demanded the position of artistic director with full authority on all questions related to casting and programming. The Festival had never seen the like before!

The photograph shows Oskar Kokoschka mentioning his work in Salzburg. A nice historic document to this event, which I got for my 40th birthday .
