Alex Terrible is set to step into the bare-knuckle ring for the fourth time on Wednesday, fighting at Blood4Blood in Daytona Beach, Florida, ahead of the Welcome to Rockville festival. The 32-year-old Slaughter to Prevail singer is booked in the main event against bull-rider and bare-knuckle enthusiast Cameron Delano.

Terrible said he had no background in combat sports or martial arts before deciding to test himself in bare-knuckle fighting. He also helped organize Blood4Blood, a four-bout card he says was built to join metal and bare-knuckle boxing, and he partnered with bkfc to help promote it.

The singer said he is not making any money from the fight and put his own funds into the show so the other fighters would be paid. That line says a lot about how he sees the project. “Because I believe money shouldn’t be in the first place,” he said. “It should not be a priority. The priority for me is the art, is the main goal, is the concept, the business plan.”

Blood4Blood came from an idea one of his bandmates had about putting a fight card next to a concert, and Terrible said the goal was to turn the pairing into something fans would remember. “We want to make a combination of metal and bare-knuckle boxing, to combine this and bring this to show people how fun it can be,” he said. He added that a fan arriving for a favorite band and then seeing bare-knuckle fights between sets would get “a high f*cking endorphins and all of this shit.”

The event lands in the middle of Slaughter to Prevail’s worldwide tour, which runs through October, and Terrible said he will still play with the band the same night as the fight. That is the hard edge of this project: it is part spectacle, part personal test, and part touring schedule. Terrible said he may not be able to keep fighting for much longer if his wife has her way, but for now he sounds determined to keep going. “This is why I have this success and I achieve so much, because I believe in myself,” he said. “I’m not scare.”
