Early mix of Aphex from Archive.Org

Nice variant/prototype of track 7 Polygon Window at 26  min. A bit of Ageispolis melody at 15 min. Mentioned on Reddit by tbdballoons.

I'm guessing this was made by someone from the soundcloud releases. I've not heard that track at 26 min. Anyone know its name?

Thanks, I love those over tied TB-303 lines both tracks share.
