That performance is nuts.
Anyway, the Revolutionary doesn't scare me that much, as I started playing some of it a few years ago (when I first started, I was very overzealous... four months into playing, I played Mozart's K397 flawlessly in a recital, and my teacher praised me for it... gave me a big ego at first, so I attempted the Rev. a week later... That humbled me back down quite a bit, but the two sections I learned, I kept playing for years after.
The Tristesse Etude... I performed it about three years ago (yes, my teacher made me do it a year into playing... killed me... KILLED me
But as you can see... a year into music, one doesn't know music theory very well...I had only one semester of music theory, and my history classes hadn't reached the Romantic era yet... I didn't even know who Chopin was except that he was a Pole with a big nose that composed the Revolutionary etude. I didn't understand the middle section, and relied completely on muscle memory for playing it... It was probably the worst performance of the etude that has ever been done.
Back to Mozart...
I like his c and d minor fantasies, the 23rd piano concerto, the requiem, and the magic flute... everything else he composed (i've heard most of it... box set with everything, and i've yet to listen to maybe two cd's)... is... well... today's pop-music.... i just get really bored with it and being able to predict each chord progression really bothers me.
