The other members of former Iron Maiden singer Paul Di'Anno's current band, Architects of Chaoz, say they're finding a new frontman — and it's a decision he insists they'll regret.

As previously reported, Di'Anno suffered a health scare earlier this summer when doctors discovered what he described as "a massive big black shadow" on his lungs. Although it turned out to be a "rugby ball"-sized abscess instead of the cancer they initially feared, the resultant procedure and recovery time forced him to miss a series of tour dates — and this setback, along with the other issues he's faced during a long period of ill health, have left the band ready to move on without him.

Calling the decision "maybe the hardest thing imaginable for us" and insisting it's for Di'Anno's "own health and dignity," the group posted a Facebook update explaining to fans that the situation had simply become too difficult to continue.

"Many of you have seen Paul suffering on and off stage during our last tours," reads the post. "His health got even worse during the last months and as much as we hoped that there will be a surgery that gets him back on his feet, we had to find out that it is not going to happen. Trust us, nobody shed more tears over this than we did, because the five of us have spent the last eleven years together and if there ever were brothers from different mothers, it was us."

That sentiment doesn't seem to be shared by Di'Anno, who's posted a rebuttal on his own Facebook page. Referring to the rest of the Architects of Chaoz as "my so-called German bandmates," he vowed to block them from using the band name and said he'd be putting a new lineup together soon. "I hope my new AOC will debut next year with new members and an even heavier sound and energy. I'm looking at my bros in Brazil for this. Goodbye traitors!"

Whatever happens next, it seems likely to happen soon, and with plenty of exclamation points. The remaining members of Architects of Chaoz have told fans that their next album, the follow-up to 2015's League of Shadows, is "already written" and they intend to enter the studio this fall to "start a new chapter and find a new singer who can transport the energy!!!"
