My list points out that radio and charts were dominated by bands that were not rock. I would also take every pre-Wish You Were Here Pink Floyd album over the 1975-2000 albums.
When I discovered the Beatles in 1975, they stood out from the crap I was hearing (yet it was hippest at that point to snub this band that broke up a few years ago and hype their solo material instead).
Even late 70s rock is not so much rock and roll.
The term has been co-opted to mean "cool music listened to by young people" when so little of it has ANY relation to rock and roll.
That depends what radio stations you were listening to. The long-gone KMET in L.A. was rock and roll to the core. KLOS and KROQ (in the same area) were also damn good.
I would also take every pre-Wish You Were Here Pink Floyd album over the 1975-2000 albums.
I'd include Animals ('77) in that pre-'75 bunch. ......and perhaps even The Wall ('80).
Even late 70s rock is not so much rock and roll.
The Stones' Some Girls sure was, as was Aerosmith's Rocks ('76), Skynyrd's Street Survivors ('77), Zeppelin's Presence ('77), Neil Young's Rust Never Sleeps ('78), Petty's You're Gonna Get it ('78), Ian Hunter's You're Never Alone with a Schizophrenic ('79), UFO's Strangers in the Night ('78), Bob Seger's Night Moves ('76), George Thorogood's early stuff. ......there was quite a bit out there if one knew where to look.
Yeah, there was a helluva a lot of total junk in the 70s as well (as you pointed out). But each decade has had more than its fair share of the unlistenable. ......the 60s included.
