I saw Gillian Welch on Sat night on BBC 4,and was blown away...
She is what I think folk music is all about.....Emotional ,committed
and "crazy" with the music.   She had a guitarist accompanying her who was also really good,and the whole set had me on the edge of my seat. (Kate Rusby look and learn).
I agree with everyone who says BBC4 is the best thing to happen to folk music for years..Ake
