Have you, your friends or anyone in your immediately family met musicians in a personal setting?
My sister saw Justin Bieber as a street performer before he got famous when she was on vacation in Canada.
My Cousin twice removed, grew up near Holly Wood and knows quite a couple big musicians from when they were teens / young adults like Anthony from Red Hot Chile Peppers. Though said cousin is someone I've only met once since he's always getting into trouble or partying somewhere.
