Yeah. This is the one that came to my mind.
Dude straight up ended his career. His band members left, label dropped him and his colabs said they wouldn't work with him anymore.
Turns out he was a lieutenant in the oath keepers and the FBI grabbed him. Last I heard he made a plea deal and got put into the witness protection program.
He is the band and it can't exist without him. Even if he could continue, he'd have to rebuild it from the ground up.
It's a shame, I really Loved Demons and Wizards, the iced earth / blind guardian colab group.
... Based on some song lyrics I feel I should have seen this coming when looking back though.
