When is slipknots next tour?

As of my last update in September 2022, Slipknot's next tour is called "Knotfest Roadshow" and is scheduled to take place in North America from March to May 2023. The tour will feature Slipknot as the headlining act, along with other bands such as Ice Nine Kills, Crown the Empire, and Vended.

Please note that this information is based on announcements and schedules available at the time of my knowledge cutoff. It's always a good idea to check official sources or the band's website for the most up-to-date information on tour dates and schedules as they can change.
