alrite, shred rating
it's...fine. the song itself is pretty terrible but the main culprit is the unbearable vocals and the general nu-metal meets Stone Temple Pilots vibe, with a dash of metal (pinch harmonics, double bass fills, etc) tossed on top.
obv he's extremely proficient and it's not nearly the most self-aggrandizing wankery I've ever heard. otoh, none of it's anything any number of 14-year old guitar dorks on YT couldn't pull off, so the question becomes more about composition and how much it adds to or enhances the song.
I do like that he's not just playing a lot of notes really fast, he's using different techniques - bends, a lot of palm muting, etc - to create varying dynamics. and he stays more or less on track with the song, doesn't get totally lost up his own ass in convulsions of pointless notes leading nowhere.
when I've defended the shred here, it's basically been against the charge that all shred, inherently, enters the zone of fruitless intensification (ZFI). which is different from saying that shred never enters the ZFI, it absolutely can. Yngwie Malmsteen and that entire lineage of playing a trillion notes as fast as possible for no other reason than to do it are the canonical example.
