I know of the Manchester punk band - formerly managed by Paul Morley of Art of Noise etc, and recently reformed;

And the Australian underground rock band that broke up in 2016;

But I don't think it's either of those that you're invoking here.

What were the folk band like? I love a good drone! In fact, I've just ordered this book...!
