I'm not great judge of these things but what always strikes me is the freedom with which he plays (that isn't to say "uncontrolled") - as though there are no technical difficulties - just the flow of the music.
It is such a pity that he seems to have largely dropped out of guitarists consciousness these days. I have a couple of his LPs and intend to collect what I can, I'll then get then professionally cleaned and will then digitize (using my old Rega Planar 3 turntable) and use the noise/click removal tools in Sound Forge to clean them up. I might even get round to uploading the finished files onto YouTube.
