Simply said, he's an underrated genius in my opinion. His early works are very experimental with beautiful, beautiful melodies. Though, his ambient tracks never seem to bore because of the elaborated beats and unconventional ideas. Plus he catches a specific and identifying mood with his tunes. If i have to compare i would say it's aphex early works combined with this freaky album Druqs. Wich leads to win.
With "Idhax" he takes a different course and leaves the analoge regions into more digital and fast driven tunes. But he's amazing there as well. For me he is the most interesting original artists between Aphex, Ceephax, Amon Tobin & Infected Mushroom. KPStyle forever! :)
