I think that folk music is always happening, but you don't always know that it's happening, especially since recording devices are more common. Seems that the folk movement of the mid or late 70's was being produced in the bedrooms and living rooms of suburban teenagers like Daniel Johnston - from Austin, TX. Other kids living in the Bronx were making and sharing mixtapes of a new way of making folk music, and they called it "hip hop." It was also called the "Do It Yourself" movement or DIY. Does anyone know anything more about this?
