If I practiced for 3 hours every day for the rest of my life I wouldn't be able to play as well as that guy. Yup, it was a load of scales and twiddling, but all superbly executed as far as I could hear. I don't think what he was doing needed any kind of groove, no point sitting there paddling the E however well timed it might be - it was just exactly what it was - high class fretw@nkery. I've heard famous fretw@nkers do less when soloing in front of a camera. Be nice to hear him playing in the context of a band, hear him sit back and just do some of those lightening licks once in a while, some nice little fills.
Just my opinion, of course, but I think there are some rather harsh judgements going on.
