WHEN it comes to planning the Canberra International Music Festival, artistic director Roland Peelman wants to have his Sachertorte and eat it. For he has no intention of being straitjacketed by whatever title he puts to the festival, so that the 2021 motif, “The Idea of Vienna”, will be balanced by a formidable program of indigenous Australian music performed on each day of the event. To be sure, as the program reads, Vienna is “the city where Schubert and Strauss were born. The place where Haydn, Mozart and Beethoven made history. The opera house that Mahler transformed for the 20th century. The circles where Schoenberg foreshadowed the tragedy of two world wars”.
