The fairytale version of becoming a rockstar always starts with the person knowing their whole life that they wanted to be a musician. However, the reality is that that's not always how it goes.

In fact, it typically isn't.

You probably already know that Kurt Cobain was a janitor before he made it big with Nirvana. Or that Sebastian Bach was a landscaper. But did you know that Tom Araya was a respiratory therapist before he became the frontman for Slayer, or that Serj Tankian owned a software company before System of a Down even formed?

So, we compiled a list of 12 rock and metal musicians who had other careers before they made it big.
