Description: Composer Thomas Adès conducts the Metropolitan Opera premiere of his 2004 work, which has been widely praised as a modern masterpiece. Director Robert Lepage recreates the interior of 18th-century La Scala, including the hidden workings underneath the stage, where Prospero, the banished Duke of Milan, practices his otherworldly arts. The magnetic baritone Simon Keenlyside stars as Prospero, a role he has sung to great acclaim in London.
