The young Austrian pianist Till Fellner suffered a debilitating case of tinnitus (a hearing disorder) in 2005. It almost ended his career. But with medical help, he came back, playing even more beautifully than before. Two hundred years earlier, another young German-speaking pianist was devastated when he began losing his hearing. There was no medical cure for him, and Ludwig van Beethoven lived out the rest of his life in silence. In today's show, Fellner plays a Beethoven sonata, from a concert last month in London.
