I love it. It's kind of a bitch to play, no matter which instrument you're playing - partly because it's so repetitive, but also because as "crescendo" progresses, in the strings there are more and more notes to play (like line after line of awkward quadruple-stops), and it's just generally difficult to sustain the necessary stamina for that long. But it's a cool piece.

You're not going to feature this, but I once heard a virtuoso accordionist play an absolutely mind-blowing arrangement of Bolero. You had to hear it to believe it.
