Sloppy? Other than one point where Dave's guitar was pretty badly out of tune during a duel solo with Adrian I thought they were tight as a nun's tailgunner.
Rob Zombie was surprisingly a highlight for me. Monster Magnet, awesome. Slash, holy fuck awesome. Dimmu, zzz... Primus, holy fuck zzzZZZZZZzzzz...
Iron Maiden... peerless. Who needs a "big four" when you're Iron Maiden. Really, who use could take the stage with them and not be drastically dragging the chain? Overall it lacked the insane atmosphere of the last tour as far as the crowd/audience is concerned but on stage is where it really matters and they were simply amazing.
