I must admit I enjoyed reading that, so much that I got to google and listen to some of these artistes.
May I suggest though that you embed a few youtube links to their performances as part of your post, next you do this -- Did I say this is a very interesting series? -- that way I don't get to leave your blog to get a fuller experience. Not so much to distract the flow of the post, just enough (maybe 2 per artiste) to drive your point.
I am keeping an eye on your blog :)
