Me too. We don't know that this guy doesn't lay down a groove when he's playing in a band setting. Jimmy Johnson can be equally technically incredible, and if he were posting vids on youtube as an unknown (and similar context) I would hope to see some of those fireworks.
I enjoyed the comping with chords from the link Dave posted. In a small group setting (bass, drums, piano, or bass, drums and sax, for instance), some of this is not bad. Not my thing by any stretch of the imagination, but not inherently bad.
Let's not crucify this guy just because his fingers fly with accuracy..
