Rock and Metal Musicians Who Train Brazilian Jiu-Jitsu

The backstage dojo

Zoltan Bathory started martial arts with judo at nine. By the time Brazilian Jiu-Jitsu became central to his life, he had also learned that touring provides exactly the things a normal training routine dislikes: bad sleep, long drives, unfamiliar rooms, and a guitar that still has to be played that night. His answer was to take the room with him.

In a conversation about the backstage dojo, Bathory described calling academies in each city and inviting people to train. His own crew supplied at least two black belts, and some sessions grew to seven or eight. The arrangement also opened a second touring network. He noted that Maynard James Keenan's head of security was a black belt, as was the security man working with Dave Mustaine. A show could bring musicians, crews, and local practitioners into the same room hours before the audience arrived.

There was still a practical problem: fingers. Bathory tapes his index and middle fingers together, then his ring and little finger, leaving the hand split like a Vulcan salute. It gives the joints some protection without making a pick impossible to hold. The rest of him has been less fortunate. He has played with broken ribs, a broken fibula, broken toes, and enough wrapping to make the wardrobe department part of the recovery plan.

Bathory's competition record includes masters black-belt gold in the super-heavy and absolute divisions at the 2022 IBJJF Los Angeles Open. He received his black belt in 2021 and now holds a first degree. The marriage between touring and grappling is literal too: Bathory is married to Heather Grace Gracie, a granddaughter of Carlos Gracie.

Maynard James Keenan belongs to the same backstage circuit, although his path started much earlier. The Tool, A Perfect Circle, and Puscifer vocalist has trained since the 1990s. He reached purple belt in 2015, brown in 2021 under Luis "Limão" Heredia, and black belt in January 2024. The promotion did not happen under arena lights. Friends and training partners celebrated at Merkin Vineyards, Keenan's winery in Arizona, where he also helped establish Verde Valley BJJ.

A careless round can cancel a tour

Dave Mustaine's first encounter with BJJ almost ended the relationship immediately. Reggie Almeida, roughly 260 pounds, put his weight on the Megadeth guitarist, who was closer to 175. Mustaine had spent years around striking arts and did not yet understand what the floor could do. He injured a rib badly enough to think he might die. The lesson he carried forward was simple: if the ground was inevitable, he had to make it an ally.

Almeida promoted Mustaine to brown belt in 2022 and to black belt in December 2025. It arrived after radial nerve palsy, throat cancer, arthritis in his fingers, Dupuytren's contracture, and decades of damage accumulated through music and ordinary life. Mustaine's talk about fighting is less romantic than the Megadeth catalogue might suggest. He says the best move is to leave, and that his last real fight was about twenty years ago.

Trivium's Matt Heafy treats the conflict between training and performance like a technical problem. His normal workload has included one to three hours of vocal practice, at least an hour of guitar, and BJJ six days a week. On tour he brings a trainer and mats, but the rounds come with house rules: no Ezekiel chokes near the throat and no wrist locks on the hands that have to play the set.

Heafy began in March 2013 and received his black belt almost exactly ten years later. He has described guitar, voice, and grappling as skills built from the floor up. None of them responds to a shortcut. That does not mean he trains timidly. He developed a particular interest in leg locks, the part of the body least likely to ruin a vocal take or guitar solo, provided everyone remembers what tomorrow's job is.

Nickelback bassist Mike Kroeger draws the line even more firmly. In a 2024 discussion with BJJ practitioners, the Rigan Machado purple belt said he had promised his bandmates not to roll live while touring. An injury in a meaningless training round could derail a production employing far more people than the four musicians onstage.

Kroeger still visits academies around the world. He walks in wearing a plain white gi with no band patches, pays the drop-in fee, and joins the regular class. At Tristar in Montreal, he found what he called a room full of killers under Firas Zahabi. Often nobody recognizes him. For the length of the class, he is simply the visiting purple belt working on open guard and butterfly.

Rikki Rockett learned the touring version of this problem before most rock musicians had heard of BJJ. The Poison drummer saw Royce Gracie in the early UFCs, met Jean Jacques and John Machado at a martial-arts event, and accepted an invitation to train. Eddie Bravo was among the people on the mat that day. Rockett was submitted roughly a dozen times and returned the next morning to sign up.

That was 1998. In January 2024, at 62, he received his fourth degree from Renato Magno at Street Sports. Rockett is careful about casual road training because every room contains somebody eager to tap the famous drummer; a damaged shoulder does not affect only him when a tour is moving. BJJ also changed what he wanted from the road. Sleep, food, and recovery became more interesting than getting loaded after a show.

The stakes became larger in 2015, when Rockett was diagnosed with oral cancer. He later said that years of difficult rounds had made him less frightened of treatment and helped him endure it. His point was not that jiu-jitsu cured anything. It was that voluntarily staying in hard positions had taught him how not to panic when the position was no longer voluntary.

New York hardcore was already there

Years before backstage mats became social-media content, New York hardcore musicians were walking into Renzo Gracie's academy. Cro-Mags founder Harley Flanagan started there in early 1996. He competed from 1997 to 2012, taught at the school, and eventually received his black belt from Renzo.

One photograph on the academy wall stayed with him. It shows Renzo after Kazushi Sakuraba broke his arm in their 2000 fight, not Renzo celebrating a victory. Flanagan read the choice as a lesson in how a person carries defeat. The man in the photograph had lost the match without losing his composure. For somebody whose childhood and early music life contained plenty of real street violence, that distinction mattered.

Flanagan has said that, had MMA existed as a viable path in the early 1980s, he might have followed it instead of fighting in streets and clubs. Jiu-jitsu did not erase that history. It gave the aggression a room, a coach, and an end point. His account of Renzo Academy is not a story about becoming harmless; it is about learning where violence belongs.

Biohazard's Billy Graziadei began even earlier, in 1993. His tours could last eighteen months, so he sometimes brought the academy with him: instructors Luis Heredia and Carlos "Cazé" Muniz joined the road, while visits to Renzo, Royler, Rickson, and Rorion Gracie kept the training moving between cities. Before Knotfest in January 2016, Graziadei rolled with Matt Heafy, connecting two generations of heavy musicians who had built BJJ into the working day.

Agnostic Front vocalist Roger Miret offers a rougher picture of what that working day costs. During cancer treatment he underwent two surgeries and spent time in a hospital under COVID restrictions, unable to see his children. On the same floor, staff posted notices about newborns while other patients were dying. He recovered, returned to the stage, and kept training jiu-jitsu.

Miret was 61 when he talked about that period in 2025. His mother had started asking him to stop jumping around onstage. He did not. Offstage he could look like somebody's father; once Agnostic Front started, people unfamiliar with the band would ask what had just happened. Jiu-jitsu belongs to that same stubborn physical rhythm.

Crowbar guitarist Matt Brunson is the quiet heavyweight in this group. Bandmate Kirk Windstein said in 2025 that Brunson holds black belts in two forms of jiu-jitsu. The detail surfaced during a deliberately ridiculous question about which Crowbar member should wrestle an alligator while the band played "Bleeding From Every Hole." Windstein picked Brunson to do most of the work, predicted that drummer Tommy Buckley would run, and ruled himself out on the condition of his back and knees. It may be the most honest division of labour in sludge metal.

From Atlanta straight edge to Sydney hardcore

The link between hardcore and grappling did not end with the New York bands. Thomas Pearson, vocalist of Atlanta straight-edge band Foundation, left a competition trail under his full name, Thomas Anton Pearson. Representing Outsiders Jiu-Jitsu, he won bronze at purple belt in the Master 2 heavyweight division at the 2023 IBJJF Atlanta Winter Open, after competing at blue belt from 2020 through 2022.

Foundation had already played its final show by then. The record is a small but revealing reversal of the usual musician story: the band ended, while the rounds and tournament weekends continued. Pearson did not need an active release cycle to keep showing up.

In Sydney, SPEED guitarist Dennis "D-Cold" Vichidvongsa belongs to a younger hardcore scene in which martial arts imagery is no longer exotic. A 2025 interview devoted to his BJJ life focused on discipline, community, and the overlap between the room around SPEED and the room around an academy. Jiu-jitsu appears in the band's world as a practice, not a costume.

No borrowed philosophy

Dávid Makó, the Hungarian musician behind The Devil's Trade, gives the least polished answer about what BJJ has done for him. He does not say it rebuilt his personality or handed him a philosophy. In his version, it added a set of skills and some permanent injuries. If a sport completely changes a person, he suspects there must have been an empty space waiting to be filled.

That scepticism makes his description of training sharper, not weaker. Makó calls BJJ a combat sport first. Any philosophy comes from the person who enters it. What the mat does provide is exposure: a training style and a fighting style show character, including the parts a person would rather conceal. He found a home there because that bluntness already fit his world.
