Yeah I own "I Care Because You Do", the soundscapes and "architecture" (I don't really know if there is a musical term for the structure of an album) of all of Aphex Twin's albums are very interesting. Honestly I think he's kept me from listening to OTHER music because I like his so much. If you listen to "Drukqs" you'll notice that he is often violently hitting the listener with fast beats and projecting these ridiculous noises, only to bring the listener back with a soothing mechanical melody that they are used to. In a lot of ways, he's like a modern day Satie, pushing against what is accepted in music, a modern genius, rejecting norms, creating genre. It's very interesting.
A lot of his music has parts that sound deceptively simple or mundane, but then the throws in another track or few that takes it to a completely different place than you could have ever predicted, which is rare enough, but that place actually sounds awesome which is rarer still.
