Technique vs. Communication

I watched a classical guitar player a few weeks ago. I say "watched" rather than heard because no matter how often I tried to force myself to listen to the music, I found myself watching his hands instead. Marvelous technique. How does he manage to do that? Wow, look at those hands move. I can still mentally see the performance, but I can't hear it at all. How great it would have been if he had included the audience in the music.
