He was on a roll there at the beginning. I haven't heard anything after The Harrow, and as far as I'm concerned, you really couldn't go wrong with any of his releases up to that point. My favorites are Ampos, Plasma (using Stephen P. McGreevy's ELF/VLF magnetosphere recordings), and The Harrow. Dolmen Factory and Polonoid are also pretty great. I don't think his collaborations are as good as his solo work, though. That's nothing unusual, and it is again the case with Bad Sector.
