Carlos Kleiber conducted one of the greatest Opera performances I have witnessed at Covent Garden, Othello. We heard it twice in one season for an odd reason. Domingo was to sing the role that year, conducted by Kleiber, and in the same season, Jon Vickers was to sing Tannhauser. Vickers had not sung the role of Tannhauser before, and during rehearsals he said he would not perform the role, as Tannhauser was a Nazi! What happened, therefore. was that he sang Othello instead, so 2 performances a few months apart, by two of the greatest tenors of the time. Personally, I thought Vickers was marginally better, not just because he was a client of my law firm! So Kleiber conducted Domingo, and Colin Davis, vickers. Interestingly, Margaret Price sang Desdemona in one production, I think with Domingo. My younger son was being taught trombone, by David Chandler, who played in the Orchestra at Covent Garden, and one parents' evening, asked me to say what was the best performance I had heard at Covent Garden. I said Othello, with Kleiber, and David Chandler agreed. He said that I wouldn't hear him again, there, as he wanted too many rehearsals, and management couldn't afford it!
