Slipknot will celebrate the 25th anniversary of their self-titled debut album with a slew of headlining shows across North America.

Announced today, Slipknot’s North American tour will kick off on August 6 at Noblesville’s Ruoff Music Center. The trek will feature support from Knocked Loose on all dates with Orbit Culture and Vended playing on select dates.

The trek concludes with an appearance at Knotfest Iowa on September 21. For this one-time-only festival performance, Slipknot will play a special set drawing heavily from their 1999 self-titled debut album. The lineup for Knotfest Iowa also features Till Lindemann (Rammstein), Knocked Loose, Hatebreed, Poison The Well, GWAR, Vended, Dying Wish, Zulu, Twin Temple, Holy Wars, Swollen Teeth, Spine, and Dose.

Tour dates can be seen below. Pre-sale tickets for Slipknot’s newly announced headlining shows as well as Knotfest Iowa can be made here. Tickets for their tour and Knotfest Iowa will go on sale to the general public this Friday (May 3) at 10 a.m. local time.

Released in 1999, Slipknot’s self-titled debut album became one of metal’s best debut albums ever with over two million copies sold in the United States. Tracks such as “Surfacing,” “Spit It Out,” and "(sic)" have become set staples for the band.

Slipknot guitarist Jim Root said this about the record:

“We loved what we did with the first record but we didn't even know if there was gonna be anything after that. We just wanted people to hear it. Selling out of records and shows, having successful tours– those are goals for any band. But the dream scenario in some ways, came true for us.”
