Will, I think my previous post sounds more negative than I intended. I agree with you that effective communication uses all appropriate means.

Being 'of a certain age' myself, I was a teenager when folk music was fashionable among students and I wanted to be a student.
I've no way of knowing whether, in a different era when folk music was less fashionable, I would have taken the time to listen.
Unfortunately, I think that's the real problem we're up against at present.

But you're right. We can at least make the music available, attractive and accessible by all possible means and see what happens.
