Just got back from seeing them in Vancouver. I was really impressed. They put on a damn good show.
We were right up at the barricade, only a few feet from James and the boys. Near the end of the show they dropped hundreds of Metallica beach balls from the ceiling. Very cool.
Lamb of God were awesome as usual too (saw them in 2006 when they opened for Slayer).

Damn, that's awesome. I just hope they didn't play 90% of the concert with their new songs. As I've heard, Hammett isn't even capable of playing some of his old solos...

They played a pretty good mix of some old and new (and cut out their material from the mid90s-early2000s era)
I was a bit skeptical myself but everyone including Hammet played pretty damn tight.
