not weird really, its pretty common for singers to have little to do with the writing process of the actual music, so i can see how he can still tour. actually i think its weirder for jim to just not do the tour.
With an impending Slipknot album on the horizon, Jim will not be touring with Stone Sour this winter. Everyone involved is okay with the decision and our mutual friend Christian Martucci will be filling in on guitar. It was a difficult decision, but as the fans have wanted another Stone Sour tour and Jim had responsibilities to the writing process with Slipknot, we feel this is the best decision where everyone wins.
