Yeah, good list but surely missing many artists... I like all what are mentioned but have weak spot for Pete Namlook most, then Robert Rich, Brian Lustmord, Steve Roach and Biosphere... I could easily add Plastikman ( Richie Hawtin ) cause he made pretty much ambiental albums with this project. Vir Unis is great but haven't heard that much of his stuff, still have to catch up his opus, Brian Eno, the pioneer of contemporary classical and ambiental music surely deserves to be mentioned.
