I'm with you on that. Every now and then I scan the FM dial and can't believe the garbage that passes for music these days.
I've always contended that the best music and the best bands came out of the 70's which I bracket from 1966 to 1984. The creativity and momentum generated during that era was invigorating and historical. It was a time when the wide genre of rock and roll gave people something to like whether it was real power rock like Led Zeppelin or the gentler offerings that found their way onto the charts like Loggins and Messina or Jackson Brown.
I would put Zeppelin and Rolling Stones at the top of my list and then add a second tier of many bands that didn't quite have the staying power but, produced loads of great stuff; Eagles, Elton John, Doobies, Robin Trower, Fleetwood Mac, Santana, Bowie, REO, CSN&Y, Skynard, Marshall Tucker, Bob Seeger, Allman Brothers, Bad Company - the list goes long, doesn't it?
And although your question was about rock bands, I have to give my appreciation for groups like Pink Floyd and Moody Blues who were masters at creation.
With all that being said and me being a self admitted fan I have to add that there were some financially successful groups that don't get my vote: The Beatles were creative, but I never considered them a rock band. I mean; what the heck kind of a song is Yellow Submarine, do you dance to it or tap your feet? And the after birth of Wings or Paul Macartney, solo performer showed me nothing at all. I can't stand to listen to any of his schmaltzy rubbish. ...never saw what got people interested in the Doors, either, maybe it was their concerts. I saw a lot of concerts and groups in the 70s, but that was one I missed (or ignored).
I agree. Something for everyone in those days. So much talent. I can’t listen to most of the crap these days. Thankful for oldies stations and Youtube.
