Well, although it will probably not be "authentic" enough for my taste, I'll give it a listen. My daughter has already introduced me to Jake Bugg, so I'm keeping an open mind.

Even if the distinguishing characteristics of "folk" in thsi instance are simply that singers use their own, distinctive voices, and that you can hear the words of their songs, and that nobody performs with half-naked backing singers[1], that's got to be a big inprovement on much of what passes for popular music.
