The big difference between this tour and Ozzfest is that Ozzy alone can sell Ozzfest tickets. Lamb of God were co-headliners in 2007 on Ozzfest, not that they can really sell Amphitheaters, but because people went to Ozzfest mainly for Ozzy, some people even show up late just for Ozzy. I'm sure the Mayhem people are crying that they can no longer get Disturbed. People here said the year they had that short Ozzfest(2010), more people were at those than at the Mayhem's at the same venue.
