Nunn, with menacingly angular, swiftly changing sets by Rob Howell, has dispatched an expensive, slick production. Rattle's tireless dedication and subtlety in the pit were matched by expert orchestral playing, notably in the conspicuously busy woodwind. The cast, too, led by the dazzling Austrian mezzo Angelika Kirchschlager as the Polish exile of the title and American baritone Rodney Gilfry as her insane lover Nathan, excelled.
