That is really cool and the music enhances it. Sort of reminds me of the "Once in a Blue Moon" video with giant New Zealand trout going crazy during a rare "mouse hatch." New Zealand must be an awesome place.
I actually saw some brown trout doing this on the Pere Marquette fly only section a couple summers ago. Pretty cool to see happening, although I didn't have a blue damsel dry on me at the time so a little frustrating.
