The challenge for today’s artist is “what new is there to say”when referring to folk artists the word ‘untainted’ usually means untalented

I’m not sure what you’re asking here but I would say that “untainted” usually means authentic, not untalented.

"Wheels of Change", a book written by Sue Macy, centers around the progress of history most particularly ladies' opportunity. In Chapter 5 of this book, she gave authentic setting through giving instances of movements in social qualities.
