I attended, alright. It was awesome! The band was really tight, probably mainly because the audience was really into it. People (including me) were literally screaming along and though Roskilde is pretty strict when it comes to security, the people in the pits were going crazy.
Trent really seemed happy and ended the night by stating that Roskilde Festival is one of the best festivals in the world. Not a bad compliment, really. Robin also seemed really into it. Then again, there were probably quite a few other fans there who were relieved to see him with NIN again after the great G'n'R failure of 2006.
I can't recall the setlist order, but I'm pretty sure this is all they played, in no specific order:
Somewhat Damaged
Terrible Lie
Heresy
Metal
I'm Afraid of Americans
March of the Pigs
Piggy
The Fragile
The Becoming
Gave Up
La Mer
Gone, Still
The Way Out is Through
The Day the World Went Away
Non-Entity
Wish
Suck
Burn
Survivalism
Hurt
The Hand That Feeds
Head Like A Hole
I was up front, close to Robin, and had a pretty good view of Robin, Trent and Justin. Ilan was a little harder to keep track of from my spot. However, I did notice that Rob was filming Somewhat Damaged (the opening song), so we'll hopefully get to see that YouTube.
So, yeah, brilliant show - one of the most important concerts of my life. Whoever stated that their performances are off was wrong. They were great and I'm glad I got to see this line-up.
