Just got back from the show
Thoughts:
The opener was eh, but what do you expect...
Lamb of God was pretty good, I really enjoyed Ruin and Laid to Rest.
Metallica was amazing, they played about half of death magnetic, with parts of Black Album, Ride The Lightning, ...and justice for all, and Kill 'em all mixed in. The best personally were Master of Puppets, Day that never comes, nothing else matters, and Enter sandman.
I got a ticket last minute on craigslist for $60, ended up in the 100 level seats...I probably would've enjoyed it more in the pit, but whatever..it was well worth it nonetheless. I'd say at this point if you haven't seen them yet, go do it...you won't regret it.
