I have been listening to a few of the acts Ron mentioned. Danielle Miraglia - white girl sings the blues, same as Janis Joplin or Patti Smith. I guess she'll pick whichever genre description her agent wants and carry on doing the same stuff.

But Tripping Lily??? they're a younger version of Janet Klein, i.e. they're doing something highly specific that you'd expect to have a name of its own (though I don't know what it is). Why on earth would they want to call themselves "folk" of any sort?
