You can't blame only them though... the lineup yesterday was pretty weak and the acts were pretty irrelevant with each other. There were too many metal acts to be on the same day with LP. Lamb of God, Machine head, Killswitch Engage,Trivium and Motorhead refer to very different fans than Linkin Park's fanbase. No wonder why most of the crowd weren't feeling Linkin Park's performance.
Edit: Ok fuck what I said, I am watching now Enter Shikari's performance and they are not moving also O_____O Crowd was fucking lame as hell because they were stupid xD
