The performance sounded pretty good on my surround sound system today, but I could deffinitely see they didn't mix it that well in post. The vox and the guitar were really muted.
I don't know if anyone mentioned this, but Dean and Rob were using new guitars. Dean was using a Tele with a Humbucker as opposed to classic 'burst tele, and Rob was using a sunburst Schecter J-bass that I've never seen before.
