Richard D. James tends to zigzag wildly from style to style; to follow his catalogue is to court the most dizzying mental whiplash. In addition to the hyperkinetic braindance of classics like "To Cure a Weakling Child" and "Hangable Auto Bulb", he's made drifting ambient ("#1," "I"), face-melting rave ("Digeridoo"), streamlined acid house ("GAK 4") and even quiet piano etudes ("aisatsana [102]").
