This is probably my favorite Aphex album and will remain so unless he releases something even more mind****ing. I used to really not care for this album, but the piano pieces (a la John Cage) explore simple melodies and expand on Cage's concept almost flawlessly. The more electronically oriented tracks are absolutely bonkers, and they kept my interest at first until more experimental pieces finally set in. The sheer amount of variety on this album was pretty exhausting at first, but it's now become one of the reasons I adore it so much.
