Ver Cuevana 3. Performed at Madrid's historic Teatro Real in 2018, Ivor Bolton conducts Benjamin Britten's opera based on Lytton Strachey's 1928 Elizabeth and Essex: A Tragic History. In her repeated clashes with the Earl of Essex-a longtime favorite of the queen who was ultimately put to death for treason-Elizabeth I is depicted as flawed and vain, human and sympathetic.
