Starts with Josh Freese & TR shooting the shit about shitty hotel rooms and the venue barricade, then it gets better... they take requests from the few fans who got in early. Both of the songs from this performance were also webcast (not the IEM feed, obviously, just camera audio) on The Spiral by Rob Sheridan, whom I can remember filming Alessandro texting during a part in "Please" when he wasn't playing anything, haha.
