Yeah, that was my problem with his music. All technique, and little or no emotion.
Frank Zappa kinda summed it up years ago when he compared Jazz players to Blues players: (paraphrasing since I don't remember the exact quote) "Jazz guys play reams and reams of gnat notes in half a second, while Blues guys play one note and hold it out for hours while it goes squirm squirm squirm"
.... as only a Zappa could phrase it :)
