For classic rockers, every year will suck from now on. Reaper gotta reap. What year would you say classic rock stopped? I guess 1989 would be the cut off for new "classic" artists.
1979...To me, The Cars and Def Leppard are 80’s rock. Classic Rock ended with new wave and hair bands. OTOH, SRV is classic rock, so I suppose most would agree with you, and say 1989. You sure hear a lot of Bon Jovi on classic rock stations. When did classic rock begin? Beatles?
I'd say "Classic Rock" started around the cusp of the 70's, after the SF psychedelic bands had exploded, and The Allmans and Southern Rock was beginning. The British Invasion, of the 60's, and the US Pop rockers around them just missed the category, but it gets fuzzy. I'd include the 80's bands of the genre. Funny to think at the end of the '80's, BOC had been artists for 18 years. In the 90's, rock had begun to crap out as a form, with exceptions of course.
