Really surprised about La Campanella winning versus Hammerklavier. I know it has an edge on reputation, but Hammerklavier has a difficulty reputation too and is much more difficult. The more I hear La Campanella the more comprehensible it gets. But Hammerklavier is one of the craziest non-Sorabji fugues ever written.
