Fripp has got to be one of the most technically efficient guitarists on the planet. Check out the close-ups of his hands, and you'll see what I mean.
On top of that, there are some awesome guitar tones all over this song.
He's efficient because he's designed his playing around his extended-range tuning. He's such a monster player.
