Slipknot played Sonisphere in Knebworth England yesterday and as earlier reported they had a 2 minute silence in remembrance of late bassist Paul Gray. Now this video of the tribute is kinda cheap because whoever posted it has turned the volume down to represent the silence. But from the stories I've read the whole place pretty much fell silent, which is hard to do with tens of thousands of drunk rock fans. Either way, here's the video.

Even better is this video I found of them doing "Surfacing" as their last song, and then the whole band pays tribute on stage and takes pictures with Paul's jumpsuit and bass. It's really cool to watch them after their set on stage with the huge crowd cheering after.
