I also love Boards of Canada... Geogaddi is one of my all time favorite albums ever. Campfire Headphase wasn't bad IMO it was just a different approach using different dynamics by incorporating the accousic guitars. And I think, you cant really expect them to top Geogaddi, that album is just a masterpiece. Ever try playing some of the tracks off there backwards?... it reveals more of the brilliance of it.
