Looking at the foundations of modern music though, and so often it goes directly back to a root that is embedded in the 1960's. Many bands ran for decades beyond then, and people will still revere and seek the 60's records out.
Creatively, it was an explosion of artistic imagination - whether fuelled by drugs or whatever. Nothing since has surpassed that time for music. Yes, some sounds have come out in 1978, 1983, or 1991, that could have done just as well in 1967, but that is the litmus that they can be judged by. That 60's music could still do just as well today if newly released, says as much.
The 60's for me. Hip, groovy, and in with the in crowd baby, yeah. Swingin'
The 60's were innovative and fresh. Every decade since has built on that foundation but never bettered it.
