sound sculpting

How does Aphex Twin (and other abstract sound and beat makers; Autechre, Radiohead, etc) get the artistic control needed to create his sounds? Ive played with everything from Logic to Reason to Absynth to Battery and all seem to have good things that I like. But I'm missing the piece to put them all together.
