In news that is certainly a surprise to me, Tool have been booked to play the Japanese version of Ozzfest in May 2013. The lineup also includes Black Sabbath, Slipknot, Slash, Deftones and Stone Sour. Tool are mentioned as playing the 12th of May as the second headliner before Black Sabbath. I guess someone made them an offer they couldn’t refuse! Don’t go booking your flights just yet though – I’d wait for some kind of confirmation from Toolband first!
