I love that so many people thought of Beethoven when they heard this, because I was listening to his Symphony 9 (Scherzo?), and thought of this piece. This piece is indeed the main inspiration behind John Williams 'Duel Of The Fates' in the Star Wars films. I actually remember the first time I heard this (at about age sixteen or so), thinking it was the Star Wars music, and wondering why it was on a classical CD. Ah, to be young and clueless.
