Don Carlo, Royal Opera

It finally came just over three hours in. Ferruccio Furlanetto’s gouty Philip II leans his elbow on his chair and begins to grind his head into his right-hand like he's a human pestle and mortar. He first castigates himself for ever having thought that his wife, Elizabeth of Valois - who he suspects of sleeping with his son, Don Carlos - might have fancied his unyielding, aged presence, and then tries to sing his way out of his tortured predicament.
