First my rant...I cannot get the May issue part of this forum to work...
So, I will post my comment here. I disagree with SG's contention that the decline in Rock & Roll had anything to do with the rise of the CD. You confuse the media with the message...Rock, and with it record sales, are crashing because new media simply is too easy to copy and those copying do not seem to be aware or care the quality of much of what they copy is simply put, crap.
Yes, there has been a vinyl renaissance of sorts but the lack of quality in the music remains and the vinyl sales are still tiny.
I have always believed 90% of all music sold was crap in every age. Over time what has merit survives and the dross is forgotten.
