Deathcore supergroup The Big Six hasn’t released any music yet and they’ve already undergone a lineup change.

Attila vocalist Chris Fronzak has announced he’s stepped down from the group and has been replaced by Spite vocalist Darius Tehrani. Fronzak said his busy personal life and upcoming schedule with Attila would hold the group back, and is stepping down to make room for Tehrani.

“I’ve had an amazing time with The Big Six. This project has blown up way bigger than any of us could’ve ever anticipated,” said Fronzak. “However, between Attila, my personal endeavors, and my family life, I don’t really have the time or the effort to focus on this project anymore and I do not want to hold the guys back.

“So I’m announcing that I’ll be stepping down from The Big Six, and I just want to say I genuinely appreciate all the support from everyone out there. It means the world to me and I love you guys.”

The Big Six also issued their own statement, saying “Announcement: We are incredibly excited to announce Darius as a new member of The Big Six! Darius will be stepping in for Fronz and we are very excited for the future. Please give him a warm welcome and stay tuned for additional tracks and news!”
