I was looking for a composer with whom to celebrate a landmark that makes me supposedly "mature" (give or take a bit) and realised that there is only one possibility.
We take him for granted. He's everywhere. We learn about him (if we're lucky) when very young. As Schnabel said, his music is too easy for children and too difficult for adults. But more and more, he becomes one of the wonders of the world, in any way, shape or form.
Enjoy our beloved Mozart.
