A Leaf and Fallen

I recently discovered an mp3 file that had been lying around on my hard disk for a long time, maybe years, that I'd never gotten around to listening to. It's called A Leaf and Fallen (mix) and is about an hour long. I burned it to a CD and listened to it in the car and liked it, but I can't remember where I got it. On the theory that maybe someone I know gave it to me, or even made it ... do any of you recognize this?
