Electronic music is a lot more enjoyable when it's not trying to be a proxy for any other kind of traditional sound making - i.e., guitar, bass, drums, horns, strings, etc. Aphex Twin isn't trying to mask the electronic nature of what he's doing, rather, he celebrates it. He toys with it, playing.
Aphex plays with the music as a cat would: batting around and pouncing, only to casually retreat and relax, but returning again and again from different angles, different postures, different positions. Partly for fun, partly to exercise its essential nature. Paradoxically unpredictable yet patterned, regular, rhythmic.
When music becomes too perfected by the technology and tools used to make it, all the humanity, art, and soul is squeezed out. Electronic music is especially susceptible to this problem. The sense of play is gone. Rather, it become a prescribed idea of what music "should" be, what you'll buy, a way to eliminate all risk artistically and economically. (Essentially everything that sucks about the world today.)
SO, it's incredibly rare when someone avoids the trap of electronica - its tendency to be a soulless proxy for human-centered art - and creates something unique and interesting, that takes risks, and stays true to its nature.
