I have to say I was surprised. They not only pulled off an hour and a half version of the show, but it kept up the ridiculous feel of the 15 minute program. I loved it. And if you go, make sure you're on time. You do not want to miss the opening sequence.
Nice to see Mastodon do the song at the beginning. I've only recently become a big fan of them. (Check out Blood Mountain for one of the most amazing metal albums I've ever heard.)
