I am always interested in what's going on in the music field. Self-promo is fine with me because I can learn who is doing what, where and how. I think most of us here on Mudcat can cut through advertising hype and get to the root of what the artist is all about.
There is a great degree of sophistication about folk music on this website and it doesn't hurt if artists want to promote themselves. I think it's appropriate because without their blowing their own horns, who's going to know about them?
I think that Mudcat serves a purpose here of information about new artists and their music.
