Mozart in his teens and early twenties was very fond of bottoms, poo, wee-wee, jokes about kissing arses and, above all, sexy games with the delightful young ladies of his acquaintance (and why not - what have I missed!) As he got older, married, and burdened with debt and family tragedies, he got more serious about life, and I've always regarded his last decade as the most sublime and productive period of creativity of any artist in any genre. I have a sneaky suspicion that he may not have been the nicest chap on the planet, but hey ho. And, for me, the Magic Flute is the perfect work of art (I'm not being original in saying that). But his quartets, quintets, later symphonies, all his operas of that last ten years and around ten of his piano concertos are miracles. And that Sinfonia Concertante. Give yourself ten minutes and listen to the finale of the Jupiter then tell me you haven't listened to sheer genius!
