One of the grad students at USF is playing this in our February concert, and I'm in the small chamber orchestra that will be accompanying her. This is the 3rd movement of the piece, and while at first I was pretty intimidated by it, I've come to love it. It's so crazily frantic, "darkly passionate", and extremely challenging (even the accompaniment part). There are so many fantastic moments in it, my fav being 2:48. This recording feels pretty slow, so just imagine it much faster.

And, ignore the creepy picture of Hartmann.
