And while The Agonist have confirmed her replacement, White-Gluz sounded a tone of regret that she wasn't given the chance to continue fronting both bands.

Gossow says in a statement: "After 13 years of pure f***ing metal, six studio albums and countless tours, I feel the need to enter a different phase in my life. I'll remain business manager of Arch Enemy and I'll continue to develop my management roster. I'm staying true to my heavy metal roots - just leaving the spotlight, so to speak.

"I've known Alissa as a fear friend and superb vocalist for many years. I always thought she deserved a chance to shine, and now she's getting it, just like I got back in 2001. I'm proud to be part of this Arch Enemy chapter, albeit in a different way, revving up the engines behind the scenes.

"I hope to see you in front of the stage - I will join you there this time. Let the killing begin, once again!"
