I already made this thread

It was obviously not pre-recorded
Check out my band Disturbed

Also listen to the full version, his playing isn't too bad for most of the solo. It only gets bad after he cocks up and completely fails to recover. You could argue he was very unprepared to be playing a solo on a stage like that but don't talk as though he's the worst guitar player you've ever heard.
