I don't think any of the early Romantic composers knew how to write for the piano... The music of that era is full of empty theatrical gestures, full of exhibitionism, and it has a worldly, hedonistic quality that simply turns me off.

I love the early sonatas; I love the early Mozart, period. I'm really fond of that moment when he was either emulating Haydn or Carl Philipp Emanuel Bach or anybody but himself. The moment he found himself, as conventional wisdom would have it, at the age of 18 or 19 or 20, I stop being so interested in him.
