Oestvig, Karl Aagaard (b Christiania, 17 May 1889; d Oslo, 21 July 1968). Norwegian tenor. He studied at Cologne and made his début in 1914 at Stuttgart, where he sang the Lay Brother and Giovanni in the first performance of Max von Schillings’s Mona Lisa (1915). Engaged at the Vienna Staatsoper from 1919 to 1927, he created the role of the Emperor in Strauss’s Die Frau ohne Schatten (1919); from 1927 to 1930 he sang at the Berlin Städtische Oper. His repertory included Tamino, Lohengrin, Walther, Parsifal, Don José, Paul in Korngold’s Die tote Stadt, Bacchus in Adriadne auf Naxos and Max in Krenek’s Jonny spielt auf, which he sang at Munich on 16 June 1928, when the performance was interrupted by a Nazi demonstraion. A very stylish singer, he brought a lyrical approach even to his heavier, more dramatic roles. In 1932 he retiered to Oslo, where he taught singing and produced opera. Bibliography; H.
