I have to put my 2¢ in...
Can the guy play? Absolutely.
Did I enjoy it? Not really that much...

The arrogance of some musicians that believe one must be "mentally developed to be prepared, sophisticated, mature enough to appreciate the finer things in life, the depth & breadth, the nuances, blah...blah... blah..." drives me up a wall!

It's just another elitist..."the peons would never fully appreciate a fine cognac like this" type thinking.

When I listen to music, I never say to myself, "I wonder how much he REALLY knows."
Who cares? When listening...it's just a matter of taste. Not mental preparedness.
