When my daughter was in kindergarten, she had a classmate named Vortex. When I met Vortex’s mom, I found out she had named her daughter after ICS Vortex from Dimmu Borgir.
To be fair, Jay wasn’t disturbing-looking, it was his behavior on stage that stood out (he supposedly lost half his audience some nights when he came screaming up out of a coffin).*
Then again there’s Steven Tyler of Aerosmith, voted the musician parents would least appreciate having their teenaged daughters go on a date with.
*Screamin’ Jay Hawkins is the only rocker I know of who was classically trained as an opera singer.
As has been mentionned, Lemmy of Motörhead. I’m sure there was a really nice guy behind that face, but I really wouldn’t have wanted to meet him in a dark alley nonetheless. Especially if he was drunk. Plus his Nazi paraphernalia obsession kind of weirded me out.
Also seconding Henry Rollins as a dude who looks like after a couple whiskey shots he’d jokingly reminisce about that time he stomped somebody to death and buried him in the woods for looking at him funny. “Ha-ha. Just kidding. He’s really buried in La Brea Tar Pits. C’mon, I’m just fucking with you ! But don’t push me.” He was scarily effective in Sons of Anarchy. All the funnier that he’s a staunch pacifist - but he just really looks like a violent asshole, don’t he ?
