There are two sorts of performances.   The ones that leave people feeling amazed and knowing they could never do that and they couldn't even begin to try. And the ones that leave them feeling they'd love to do that, and that perhaps they could.

We've had two video clips so far in this thread. Jake Shimbukuro is an example of the first sort of performance. Paul McCartney is an example of the second.

There's room for both. But the second sort has a special kind of importance. When we criticise it because it's not the second sort, we are failing to recognise that importance.
