I'm afraid "folk music" as we knew it and as it has been for hundreds of years, has become obsolete.
The stuff produced these days has no relation to the music of the people, probably because the working class has vanished into the sunset in search of prosperity or celebrity.
The academies churn out bundles of wannabees in search of a commercial sound and the few performers with something to say have become introverted, joyless manikins.
Pop is today's folk music. Close the door when you leave the building.
