Guest 06-24am,refers to concert clubs,are these only for the purpose of offering professional performances? If so are we talking about two different things?
A folk club to me should be a balance of professional performers who give a quality act and an interesting insight into folk song and music,and non professional artists who should give as good a performance as they can.
Folk music and song after all was the entertainment of everyday people before mass entertainment as we know it today.Such music was part of the identity and culture of the people.Trained performers were scarce,
most were a little rough round the edges,but never the less played their part in society.
