Summer tours are supposed to be about good vibes, loud music, and unforgettable memories. But in 1992, the biggest rock tour of the season turned into a cautionary tale of egos, accidents, and outright chaos. Guns N' Roses and Metallica joined forces for a co-headlining stadium run that should have been legendary—and it was, but for all the wrong reasons.

The Dream Team That Wasn't

Metallica was riding high on the massive success of The Black Album, with hits like "Enter Sandman" and "Nothing Else Matters" making them the biggest metal band on the planet. Meanwhile, Guns N' Roses were touring behind Use Your Illusion I and II, armed with anthems like "November Rain" and "You Could Be Mine." When they announced a 26-date stadium tour with Faith No More as the opener, it seemed like a match made in rock heaven. But from the start, the two bands couldn't have been more different.

How Slayer's Kerry King Gave Beastie Boys Their Heavy Metal Edge on 'License to Ill'
Forty years ago, Slayer's Kerry King added thrash metal solos to Beastie Boys' 'No Sleep Till' Brooklyn' and 'Fight for Your Right (To Party)'—a collaboration that shaped rap metal and left King wishing he'd taken a royalty.

Metallica ran their shows like a military operation—tight, punctual, and professional. Guns N' Roses, on the other hand, were famously unpredictable. Axl Rose had a habit of taking the stage hours late, sometimes after midnight, leaving exhausted crowds fuming. That tension simmered beneath the surface as the tour kicked off in Washington D.C. on July 17, 1992.

Pyro, Puke, and a Lighter to the Groin

The problems started small but escalated fast. In Detroit, Axl Rose vomited onstage mid-song, then gamely restarted the track after a brief break. At Giants Stadium, a fan threw a lighter that hit Rose in the crotch, causing him to storm off and leave bassist Duff McKagan to finish the set. Rose's voice was also giving out, likely from the grueling schedule, chain-smoking, and heavy drinking. But the real disaster struck in Montreal on August 8.

During Metallica's set, frontman James Hetfield accidentally stepped on a pyrotechnic device during the intro to "Fade to Black." Flames shot up his body, causing second- and third-degree burns on his arm, hand, face, and back. The band rushed him to the hospital, and drummer Lars Ulrich told the crowd they'd make it up to them. Fans waited over two hours for Guns N' Roses to take the stage.

The Montreal Riot

When Guns N' Roses finally played, they barely made it through a few songs before Axl Rose complained about monitor issues and a sore throat—then walked off, ending the show. The crowd, already disappointed by Metallica's truncated set and the long wait, erupted. Inside the stadium, fans stormed the stage and looted merchandise stands. Outside, they overturned police cars, smashed windows, lit bonfires, and fought with police. The damage totaled over $400,000, with multiple injuries and arrests.

The riot became a defining moment of the tour, but it didn't end there. The two bands postponed six shows and canceled one in Vancouver. Metallica's guitar tech, John Marshall, stepped in on rhythm guitar since Hetfield couldn't play due to his burns. Hetfield still sang, but the tension between the bands was palpable. Metallica felt Guns N' Roses could have saved the night in Montreal, but instead, Rose was backstage smoking and complaining about his voice while the city burned.

Faith No More Gets the Boot

The final blow came in September, when Faith No More frontman Mike Patton—after a fan threw a bottle of urine onstage—opened it and poured it all over himself and Axl Rose's vocal monitor. Guns N' Roses promptly kicked the opening act off the tour. The whole experience was a mess of bad blood, bad luck, and bad decisions.

Looking back, the 1992 tour is a reminder that even the biggest names can stumble. For more on summer entertainment disasters, check out our list of zombie disaster movies that keep you on edge.
