Failing to mention, of course, that the songs played were specifically written for three-stringed guitar. You don't bust a string mid-song, written with six strings in mind, and practiced as such, while playing a six-stringed instrument, and manage to hit all the notes.I just watched this on Rothfuss' blog:
YouTube - Improvisation - Guitar with 3 strings.MP4
One of the most brilliant things I've seen this year. Guess what?
I LOVE it.
Pure BS on Rothfuss's part, and he even says so. He simply imagined what it was like to play.
