This was fascinating indeed. It's interesting hearing this from his perspective. I'm not going to call myself a virtuoso (not by a long shot), but I feel the same way he does every time I pick up a guitar. I become so caught up in the endless possibilities of what can happen, how I can make them happen, and how the sound of the instrument by itself might just be completely inappropriate for what I'm doing.
It's why I play two other instruments and sing, it's why I'm trying to learn piano, it's why I want to learn as many instruments as possible. It's so I can someday maybe make a truly beautiful piece of art and not be limited to canvas and oil paint.
