Simon Russell Beale travels to Italy to explore the story of the notorious Duke of Mantua and his long-suffering court composer Claudio Monteverdi during the turbulent times of the late Italian Renaissance. Out of the volatile relationship between the duke and the composer came Monteverdi's Vespers of 1610, a major turning point in western music. The Sixteen, led by Harry Christophers, explore some of the radical and beautiful choral music in this dramatic composition.
