These are all available now on youtube. They are all mature works but the later ones are the more powerful, all written in only thirty five short years. I never tire of listening to these concerti. I notice that the third movements of numbers 15 and 22 are both variations on a hunting theme – very pleasant to listen to. The slow movement of number 17 is the most beautiful of all. It is pointless trying to describe Mozart in words. Whenever a performer tries a cadenza not written by Mozart or Beethoven, the music immediately falls apart. This happens in a performance of number 22 on youtube. Also it becomes immediately obvious that some performers are outstanding, others mechanical and insipid, some conductors are too slow and so on. I used to take ghastly revenge on Jeremy Jones by playing Mozart in the EDCL. As far as I know he was tone deaf. I would say that string theory to Lagrange is as rap to Mozart. Rap is just like the howling of a cat at midnight darkness, as in the long poem Mari Lwyd by Vernon Watkins – ghosts knocking, a rapping at the door.
