CJ left the band back in late 2015, citing struggles with his finances and a desire to spend more time with his family.
Onstage at UNIFY Gathering, he said this:
"I was a drug addict, I was a broke musician, and I had some fucking issues... I got married, I did some fucking soul searching, and now I'm back to take over the world with my fucking brothers. In the celebration that is me coming back to join my brothers in world domination, I need you guys to have some fun with us."
Impericon Festival UK will take place on April 17, 2017 at Manchester Academy. Miss May I, Being As An Ocean, In Hearts Wake and more will also appear.
