And now the backstory: I was recording a streaming radio broadcast (this was years ago now, so I don't remember what for, or what station).

Anyway, I think this came on after the show I was initially trying to record, and I was probably out of the room with it still recording, so I ended up recycling the recording of the piano piece into the dumb little "song" I've linked to below... I never caught the name of the composer/composition, though, and I've wondered about it ever since.

I would be eternally grateful to anyone who can ID the composer/composition, or even something similar to help me get a foothold that'll allow me to start doing my own research (like whatever this could be classified as... Like, say it's "Minimalist". What era/style of Minimalism, then? That sort of thing).
