Have you listened to some Mozart recently? I hadn’t, but somehow I just felt I wanted to. This is, of course, a sign of ageing, but as long as your fine with that it may be a nice refreshing experience. It was for me. I went for Horowitz’s recording of Piano Concerto No 23 and Sonata No 13, randomly. I noticed he had not cut his fingernails, apparently: you can hear them.
