Slipknot is preparing for a two month international tour that will begin Jan. 20 in Helsinki and run through a March 23-24 stand in Tokyo. The shows will be the Iowa-based hard rock collective's first since the cancellation of a month's worth of U.S. dates, after the wife of percussionist Shawn Crahan (also known as #6) was admitted to the Mayo Clinic for treatment of Crohn's Disease.

Following the international dates, Slipknot plans to return to the U.S. for a full-scale headlining tour that will serve as a make-up for the canceled shows. The group will be touring behind its latest Roadrunner album, "Iowa," which debuted at No. 3 on The Billboard 200 and is No. 187 in its 13th week on the chart.
