I wonder what makes Turandot more explicit than, say, Wozzeck, which is about a psychotic soldier who, after suffering hallucinations as a result medical experiments that verge on torture, slits his mistress’s throat, (said mistress, the mother of Wozzeck’s bastard son, having been seduced by the army Drum Major)? Maybe in this performance of Turandot Dame Joan Sutherland and Sir Peter Pears were doing something behind the ancient pseudo-Chinese veil. Oh yes, and please protect our youth from Ping, Pang and Pong.
