I know it is not about UK folk, but I found what PFR had to say about folk from other places. He mentioned Eastern Europe and Arabic Music..I too listen to a lot of music from those parts of the world.
I wonder if he would care to share some of his favourite sites, musician info ?
   Now for a brief analogy. It has been suggested here that the lack of clubs is an indication of the decline in folk music..People say that the closing of book shops is an indication that people read less..not so. Along with PFR I think people are simply accessing books. music and culture in general, in different ways.
   I listen to a lot of music on YouTube and am hearing styles, genres and artists that could I not have heard a few short years ago.
    The other great thing is that we no longer have to restrict our playing or listening to local or national traditions..the world is there for us and music is one of the great joys..no need to define it..just enjoy it.
