I have the second edition RS rrecord guide from around 1983(blue cover). It had served me well as somewhat of a discography in years past. The thing is the ratings and the obvious bias toward certain artists. It trashes anything progressive out of the mainstream fundamental rock and roll boundries of the early 60's. For example the Moody Blues, the Grateful Dead, and Black Sabbath are worthless. Nothing over 3 stars. Also Alan Parsons project has NO stars. Does anyone else get irritated with this? I hope no one really took these rating seriously at the time.
