"Politics and religion are dangerously entwined in Giuseppe Verdi's Don Carlo. It is based on the 1787 dramatic poem by Friedrich Schiller and was first performed at the Paris Opéra in 1867. Verdi made extensive revisions to the opera over the following 20 years. This production by Nicholas Hytner follows the five-act 1886 version - Verdi's final revision of the work."
