So I did the BP Big Screen thing in Trafalgar Square again in July, with a couple of friends. Don Giovanni is an 18th-century pick-up artist who sleeps with women and then abandons them, until he kills the father of one of his conquests and vengeance catches up with him. Gorgeous costumes, nice set design, lovely evening. But opera’s surely the least accessible of all art forms: no tune, to modern ears; and most people (including me) don’t have the knowledge and background any more to appreciate it. In other words: I don’t like it. And I’ve made my peace with that.
