Discovered recently that Electric Wizard were kinda dicks back in the day. "At the time, we were pretty bad people. I got arrested for arson of a car, outside a police station. Tim [Bagshaw] went to nick a crucifix off a church roof so we could use it onstage…"
R. L. Burnside killed a man "possibly at a craps game."
Varg of Mayhem Burzum burned a couple churches and killed a bandmate.
I could list other examples, but would like to hear from other people and other music genres.
Ethan Kath abused Alice Glass enough to the point of her just up and quitting the band. She was only able to come forward when she found four other women who were abused by Kath .
