My musicians stories mostly deal with members of heavy metal acts from the 80s.
A bit of backstory:
Growing up, my friend's father was the sound man for Twisted Sister. He had a very cool house, lots of Eastern decor and crazy shit, not like everyone else's house. He also had a sound room with a sound system wired throughout every room (basement and attic, too). He was a very cool guy to us kids, too. No prohibitions on cursing, drinking, smoking, etc.
You'd think that would make his kid have bad behavior or something, but it didn't. His main rule was don't be an asshole and it worked. Free to do whatever it was you wanted as long as you weren't an asshole. We weren't getting hammered there in grade school or anything, but a safe place to drink beer and smoke in high school? Absolutely.
Apparently he was a very cool guy with the adults, too, because people would stop in whenever they were in town. I'd ride my bike over there with a 12 pack in my backpack and Eddie Ojeda and Dee Snider would be hanging out (or whoever it happened to be that day). Want to stay for steaks with the guitarists for Rob Halford's new band? We'll just throw another one on.
Very much every day life with semi-famous people hanging out for a few hours.
