SnackOn first listen it feels a bit less polished and has a sense of abruptness to it. Different sections of the songs don't really blend into one another as much as they just switch immedeatly from one to another. New instruments/sounds don't slowly inch their way into the mix as much as they just jump out of nowhere into the mix. Has some really catchy bits though.
Also slightly unrelated but I'm seeing Aphex perform in Berlin in November and I'm excited :D
