I read speculation somewhere that the first track of that album is the finished product, and the other tracks are works in progress or mood/jam palettes or investigatory scraps of various parts, some of which went unused. When I listened through with that in mind it made sense (and made the album more approachable), and the track titles may indeed support that theory. But, as with all things Aphex Twin, we are left to interpret on our own -- who knows?
