Watch Reunited BIOHAZARD Perform In Grantville, Pennsylvania

The Steve Easton YouTube channel has uploaded video of BIOHAZARD's entire September 15 concert at Hollywood Casino at Penn National Race Course in Grantville, Pennsylvania as the support act for MEGADETH. Check it out below.

Last month, the reunited classic lineup of BIOHAZARD — guitarist/vocalist Billy Gradziadei, guitarist Bobby Hambel, drummer Danny Schuler and bassist/vocalist Evan Seinfeld — confirmed that it was working on new music.

"The inspiration's coming from these shows," Bobby told Le Coin Metal in an interview. "Being back together, celebrating and doing all these shows, it's great. We're having a good time, but now we're getting the vibe from the crowd and we're feeling it, and it's getting in our bones. We're getting that hunger and the ideas are starting to come out off of these shows."

Added Billy: "For me, it's kind of cool because the other reason I did [my solo project] BILLYBIO is because there was no BIOHAZARD, and the songs that I would've been showing these guys just [ended up] BILLYBIO songs. So being back with these guys is, like… It's cool to have another outlet for my music."

The first reunion gig from Gradziadei, Hambel, Schuler and Seinfeld took place on May 26 at the Milwaukee Metal Fest at The Rave/Eagles Ballroom in Milwaukee, Wisconsin.

This past January, Schuler told Dan Shinder of Drum Talk TV, Schuler about how BIOHAZARD came back together: "We haven't toured in about seven years, almost eight years. In about 2015, [that] was the last year of touring. We wrapped it up after that. We went in the studio to go do a record and things just kind of imploded; everybody's a bunch of crazy personalities. In the ensuing years, we didn't do anything as BIOHAZARD. And then about a year and a half ago, my brother, who lives in Torrance, California, was flying back home to New York to come see everybody. And he gets to the airport here, and he says to me, 'You won't believe who I saw at the airport.' And I said, 'Who was that?' And he goes, 'I saw Evan,' the bass player from BIOHAZARD, Evan Seinfeld, who I hadn't spoken to in 10 years. And they had a good conversation, and it was cordial. And he basically sent a message through my brother, 'Tell Danny I said hi.' So a week later, I'm going on vacation. I'm feeling good. I'm going down to the beach house here in [New] Jersey with my wife and my kids, and I said to my wife, 'Maybe I should call him' — you know, just bury the hatchet. Who cares anymore? Like everybody, COVID and all these people dying and all this stuff, it's, like, who the hell cares about all that old stuff that made you mad. So my wife was, like, 'Yeah, why don't you give him a call? Don't be an asshole. Call him.'

"Anyway, long story short, I did call him and we spoke," he continued. "And we just kind of buried the hatchet. And the other guys in the band, Bobby and Billy, had been speaking, and we've been speaking, and everybody just kind of started talking a little bit. And unfortunately, our former manager, Scott Koenig, who was out in Los Angeles, he passed away. And that was a real moment where it was, like, 'Wow.' Scott was with us from the beginning, and he was like a fifth member of the band. … That was in October of '21. … I got that call. And the same week, Ir friend of ours from a band called DOG EAT DOG, our friend Sean Kilkenny passed away the same day as Scott. So it was two phone calls, two brothers, two great, close friends, like family, both passed at the same time. And for me, that was kind of one of those things where it's just, like, who cares about all the negative bullshit in the past? Who cares? We're still here. We did great stuff together. We created something cool. We should all be friends. And that was my thinking. And everyone kind of felt the same way. And that kind of was the beginning of how it started, getting the band together."

Last year, Graziadei said in an interview that there had been "talk" about putting BIOHAZARD back together.

The group, which is acknowledged as one of the earliest outfits to fuse hardcore punk and heavy metal with elements of hip-hop, had been out of the public eye since Scott Roberts left the band seven years ago.

Roberts, who played guitar on BIOHAZARD's 2005 album "Means To An End", rejoined the group in June 2011 as the replacement for Seinfeld. Scott fronted BIOHAZARD for nearly five years before exiting the band in February 2016.

In an August 2020 interview with the "Aftershocks" podcast, Roberts said that he left BIOHAZARD because he "wasn't happy" anymore. "There was one guy that I wasn't getting along with very well, and it made touring not fun anymore for me," he said. "My reason to stick around was to make a new record that was great and I'd be proud of and all that stuff, and then it became kind of clear that wasn't gonna happen, so I was, like, 'What am I doing it for?' So I quit."

Seinfeld made his last recorded appearance with BIOHAZARD on 2012's "Reborn In Defiance" album, which marked the first LP featuring the band's original lineup in 18 years.

Graziadei is currently a member of POWERFLO, which also features former FEAR FACTORY bassist/guitarist Christian Olde Wolbers, Sen Dog from CYPRESS HILL, and Rogelio Lozano from DOWNSET.

Billy's solo project, BILLYBIO, released a new album, "Leaders And Liars", in March 2022 via AFM Records.
