Incredibly executed, but there is not one melody in there that's going to pop into my head a week from now. And... he doesn't sound 'different' - and this may be a deficiency in MY ears, MY brain - but when I first heard Zappa, or Hendrix, or, hell, even Pete Townshend, the Edge - they didn't sound like anyone else... they sounded totally new.
And... I also think that high-speed arpeggios just bore me. I am in awe of the technique, but I do not find this one quarter as musical as one slowly, deeply played note. I am not against 'speed' (Zappa was fast - for his day), but what I percieve as the over-use of speed. This is my bias, I know - the pursuit of speed, worshipping at the temple of speed seems to be what it's all about for a lot of folks. I like to play fast - but just a little. It's like sex: nuance and feeling are the base, speed's just thrown in for flava.
