Thanks Riaan. I got a copy in the meantime - I've only given it a quick once over so far, but Klosterman is pretty accurate, if overall a little too positive.
Overall, It's quite simply overproduced - too many disparate parts from too many different individuals, recorded in too many different studios and all crammed together without enough tough decision making on what to leave out. Buckethead's influence is very obvious in all the robotic grooves. Axl's voice is still annoying, and it's made worse in some songs by virtually every different vocal line being a different take.
I liked Klosterman's:
"A song like "Shackler's Revenge" is initially average, until you get to the solo—then it becomes the sonic equivalent of a Russian robot wrestling a reticulating python." - pretty accurate decision of the Bumblefoot solo.
Soundclips:
(great solo at 3:10)
Pure Buckethead. Nice use of a killswitch.
Anyway, It's going to take a few more listens to really digest...
