“Isnt Mitch the guy who said Rockn Roll would never last?”
If he was, he was right. Rock ‘n Roll died a long time ago, replaced by Discordant Crap.
Let me be the first to endorse that thought. Indeed, R&R did go away, about the end of the 60s, though some may have lingered into the 70s. The stuff after that? Ugh. But, if you never heard anything but the junk produced thereafter, how would you know?
