Are people paying to see this guy?
That's always the bottom line. Play what the people want. If they want to see country, jazz, rock, etc... then they will go see it. You figure, most people are stuck at a job they don't like. They want to be entertained and have fun. If someone is having fun by watching this guy thats all that really matters.
Me personally, this guy isn't my thing. I wouldn't pay to see him. But, I would pay to see Ed Bickert or Allan Holdsworth. But, some guys who play really fast don't interest me very much. Like Bireli Lagrene for example. An incredibly fast guitarist. Very clean. But, just doesn't speak to me at all.
