I would say that everyone that you see who is successful in the mainstream, at the top of Billboard, who has a Top 40 hit. . . at some point, unless they're a complete fabrication of the industry with no identity of their own and a carbon copy clone of someone else, they in themselves started out being underground.
Any artist can't get away from the way the world works, which is that it wants to know what you did, and you're only interested in what you're doing right now.
