I once saw Leo Kottke live. He tuned his twelve-string for over five minutes, and then apologized, saying, "Sorry guys. Unlike some folks I actually like to play in tune." He then proceeded to play one of the most impressive sets I have ever seen. I wish I was born with this man's talent and creativity. If you haven't heard him yet, please buy one of his CDs or go to one of his shows, if only for your own good as a guitarist.
