Slipknot Announce 25th Anniversary Reissue With 40 Unreleased Tracks

Slipknot are marking 25 years of chaos. The masked metal pioneers have announced Slipknot (25th Anniversary Edition), a deluxe reissue of their 1999 self-titled debut album, out Sept. 5 via Roadrunner Records.

The expanded set boasts 59 tracks — including 40 previously unreleased demos, alternate mixes and live recordings — spread across six LPs, and comes with new artwork, rare imagery from the band’s personal archives, and nine collector photo cards.

Ahead of the anniversary release, the band have shared an unreleased demo of “Prosthetics,” recorded prior to their sessions at Indigo Ranch with producer Ross Robinson. The raw version showcases an early take on the track, which later evolved into one of the record’s most sinister cuts.

A limited edition run of 100 “blood-filled” vinyl copies was released to fans via the band’s secret site, 742617000027.net, selling out in seconds and crashing the website. The general 6LP box set features blood-splattered vinyl (limited to 1,899 copies), with additional formats including a 2LP, 2CD and digital versions also available.

Among the rarities included are the legendary Indigo Ranch mixes, early demos of key tracks like “Wait and Bleed” and “Spit It Out,” and alternate mixes from Jay Baumgardner and Ulrich Wild. The live material captures Slipknot’s explosive rise in real time, including a 1999 show in Hartford, Connecticut and several massive 2000 performances in the UK and Iowa.

“We loved what we did with the first record but we didn’t even know if there was gonna be anything after that,” guitarist Jim Root recalled. “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.”

Released in June 1999, Slipknot became an unexpected cultural force, going double platinum and redefining the boundaries of heavy music. It introduced the world to the band’s now-iconic nine-member lineup, frenetic visuals, and genre-defying sound. In the years since, Slipknot have racked up more than 30 million record sales, 14 platinum certifications, 40 gold, a Grammy win, and headline slots at the world’s biggest festivals.

Founding member Shawn “clown” Crahan added: “Every time I’ve walked on stage, it’s never been about how many people have been there because my culture, the maggots, always show up.”

The band’s 25th anniversary celebrations also included the sold-out Here Comes The Pain world tour, which featured a homecoming set at Knotfest Iowa and throwback-heavy setlists honoring their debut era. You can pre-save the album here.
