Mosh fiends rejoice, after 13 years of silence the legendary hardcore/metal mashup pioneers in Biohazard have reunited and are poised to drop one of the sickest albums of their storied career. Divided We Fall, out October 17 via BLKIIBLK, finds the Biohazard crew back in top form, bringing the slamming riffs, fat grooves, and abrasive attitude we all know and love.
“I had moved on from Biohazard over the years,” guitarist/vocalist Billy Graziadei admits. “I was doing a band called Powerflo [with members of Cyprus Hill and Fear Factory] and I did a solo project called Billy Bio. I was getting all these awesome vibes, good times and great tours with these bands. Biohazard had been through the ringer over the years, and I was over it. I was done.”
In 2011, shortly after recording their ninth studio album, Reborn in Defiance, Biohazard vocalist/bassist Evan Seinfeld quit the band. Graziadei and company would go on to release their last album internationally and soldiered on performing live without Seinfeld for a few years before going on an extended hiatus that would last over a decade.
“When the idea of reuniting the OG lineup of Biohazard came around, I believe it was a mixed bag of emotions for all of us,” Seinfeld shares. “Personally, I was ready and open to all new possibilities. Had this been five years earlier, I don’t think it would have been met with the same openness and enthusiasm.”
As fate so often decrees, the latest chapter of Biohazard lore began with tragedy. “Our long-time manager, Scott Koenig had passed away. I bumped into Evan at a memorial for him,” Graziadei says. “I was on the phone with (Koenig) the night before he passed. He’s telling me, he’s, like, on his deathbed, and one of the last things he said to me was ‘you should put the band back together. Bury the shit with the band. You made some great music and did something unique. Let that shit go.’”
“Biohazard is more than a band, it was kind of like a musical gang when we started it,” says Seinfeld. “You can take the boys out of Brooklyn, but you can never take Brooklyn out of the boys. When we first met up in L.A. at a house we rented near the studio, there were hugs that carried deep emotion. There was a period of us feeling each other out and seeing how the dynamic would be between us, where each one of us was in our personal and professional lives. We each, for sure, knew the level of commitment that came with it. I cried quite a bit myself, and felt my connection with each guy personally, as well as the power of the collective. Biohazard is bigger than the sum of the parts.”
Graziadei reiterates Seinfeld’s sentiment. “We jammed together and we were like little kids again,” he says fondly. We started sharing ideas, started jamming riffs and it turned into a Biohazard record.”
That record, is 2025’s triumphant Divided We Fall. Biohazard’s 10th studio album feels simultaneously old-school, yet sounds modern and executed with 21st century precision. The album’s opening track “Fuck the System” is a high-octane ripper. Drummer Danny Schuler unleashes a barrage of galloping kick drums before classic Biohazard breakdowns take center stage. Lead guitarist Bobby Hambel drops haunting guitar harmonies galore, as the uncanny vocal interplay between Seinfeld and Graziadei’s iconic screams go back and forth. “Forsaken” doesn’t relent in the slightest. More rapid-fire punk tempos, more stomping breakdowns, awesome bass grooves, and enough attitude to get even the most timid of listeners stepping “to the rhythm of the Brooklyn beat” as Seinfeld shouts during the song’s epic climax.
“With Biohazard we always have this philosophy: we call it the meat grinder,” Graziadei reveals. “Where a song starts or how it’s brought to the band—whether it’s one riff or a full song demo— we still put it into this meat grinder where we jam on it, where it evolves into a Biohazard song.”
Seinfeld describes jumping back into the studio with his Biohazard brothers, saying, “It was like putting on an old favorite t-shirt. We all play better than we used to, and our instincts are sharp. When the world hears the new album, it’s gonna be like a punch in the stomach that drops you to your knees to catch your breath. It’s not for the faint of heart,” he laughs. “Everyone in Biohazard is extremely prolific, and there was no shortage of ideas for the meat grinder.”
“We worked with Matt Hyde as a producer who I was a big fan of and got very close with,” Graziadei shares. “As we were sending him songs, some of the things we had I wasn’t feeling. He said to me: ‘Don’t try and reinvent the wheel, just be Biohazard. You guys created a style. Don’t worry about trying to write a symphony to impress Dave Mustaine or James Hetfield or Maynard from Tool. Just fucking be Biohazard.’ That resonated strongly inside me and I let go of all these other expectations.”
“I love every song on the album,” Seinfeld gushes. “Each day I find something about a different track that I might call my favorite of the day. Without giving it all away, there are special moments in songs like ‘I Will Overcome,’ ‘Warriors,’ and ‘Fight to Be Free.’ I think every MMA fighter, boxer, or savage competitor will want to walk into the ring or octagon to one of these; and for every person, Divided We Fall can serve as a soundtrack for whatever you face, to face it with all you got and rise above!”
Biohazard have returned amidst tumultuous times in the world. The themes they explore on Divided We Fall, and the raw impassioned energy they’ve brought since day one back on Flatbush Avenue in the late 1980’s is more relevant and appreciated than ever before.
“To be out there, feeling the energy, seeing how our fans had evolved and aged, and grown with us, was incredible,” Seinfeld says describing Biohazard’s first show back at 2023’s Milwaukee Metal Fest. “It felt like a 25-year high school reunion. The best part was seeing new, young fans who thought of Biohazard like it was their dad’s Black Flag t-shirt, getting into it. We live for these moments.”
“The crazier the world is, it seems like the underground subculture scene gets bigger,” Graziadei says. “The world is full of bullshit and chaos. Battling between left and right, vegan and meat eaters, of all the opposites in the world. But there’s a certain energy at underground subculture music. You’re with peers and when you release that energy you feel like a million bucks. It’s free therapy. All that pent up pressure is released. When you leave the show, just like when I get offstage, I get this cathartic release and it’s awesome. There’s nothing else in the world that does that,” he says fondly. “They say rock and roll will never die and it doesn’t.”
Divided We Fall is out on Friday, and you can preorder it from BLKIIBLK Records. Follow Biohazard on Facebook, Instagram, Twitter, and TikTok for future updates.
