‘60s Beatles, Stones, Who, James Brown, Motown, Beach Music, Folk Music, Joplin, Hendrix, Paul Revere and the Raiders. ‘70s had Almond Bros and Southern Rock, and Frank Zappa, and then Disco. Disco was not rock.
Mid 70s, the Corporations and the A&R men took over.
Disco still sucks. But all three decades had SOME decent music amid the trash, but it got thinner and thinner during the ‘80s.
