That is a very good article, of course as an old timer I would consider it so. I well remember `Dark side of the moon` released when I was in high school. Along with Black Sabbath, Deep Purple, Uriah Heep and many others we had a rich source of musical material to keep us happy. Buy even in those days there was a lot of dross on the radio. The difference was that there was investment in new and creative music.
