John Pritchard conducts the London Philharmonic Orchestra in this Glyndebourne production of Giuseppe Verdi's opera "Macbeth," featuring baritone Kostas Paskalis as the troubled soldier and soprano Josephine Barstow as his murderous wife. Bass James Morris plays Banquo and Keith Erwen portrays Macduff, with the Glyndebourne Chorus ably backing the cast and bringing the march of Birnam Wood eerily to life.
