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.
Red House Painters, specifically Mark Kozelek. I think the things he was accused of were from his Sun Kil Moon days, but it still sucks. Those first couple of albums I have listened to dozens of times.
Crystal Castles and Sweet Trip also have intraband sexual assault allegations, which really sucks because then I’m a fan of both the victim and the predator.
