I caught the first 30 minutes of that before leaving the office. They were ON FIRE. Jon was so pumped, the stage set looked awesome and Hansi was sounding killer. 4 backup singers too.
Jon was interviewed on a local metal radio station the other day and he said the same band, minus the keyboard player and backup singers, will be on the US tour. They planned to see if the Wacken footage is viable before committing to a live DVD but they have recorded every show's audio, so a live album is definitely happening at least. Plus 2 studio albums. I don't see why the footage wouldn't be good, given the amount of bands that release their shows from Wacken.
