In an interview with the Sonisphere festival website, Slipknot guitarist Jim Root reveals that the band haven't decided if they are going to continue or not following the death of bassist Paul Gray (pictured) last month.Root says that he and frontman Corey Taylor plan to be on the road for their next two years with their side-project Stone Sour, and then they will reconvene with the other members of the band to decide their future."There's going to be a big healing process that needs to happen before we even think about whether or not Slipknot will continue," he said. "And right now that's the furthest thing from our mind. "Right now we are just grieving or trying to find time to grieve anyway for the fact that our bro's gone," he added. "It's weird because some days I don't even think it's real, so that one's not going to make sense for a while."Stone Sour's new album, Audio Secrecy, will be released in the UK on September 6.
