re: How will Mumford and Sons be remembered?

As posers. They borrowed an aesthetic that they didn't really have a connection to and rode it to some fame and fortune. But they can't really do much from there b/c the foundation of their style is inauthentic: they don't have any artistic progression to make unless they can strike lightning and co-opt another style. But that will just reveal them as the frauds they were before.

Hopefully we never see them again.
