The Ninth Symphony is Gustav Mahler’s last completed work – an expressive farewell and at the same time a visionary anticipation of musical modernism. Since Mahler did not live to see the premiere of his Ninth, he could not complete his customary final revisions of the instrumental balance. “This provides a special challenge for all those who interpret this musical testament when examining the musical text,” says Kirill Petrenko. He is joined in this delicate task by the Berliner Philharmoniker.
