The way people saw themselves and the world and the great limitless sense of possibility and wonder is captured in albums like this. It was better when the world was way bigger. Tech and quick access to cheap thrills as shrunken the depth that people take the time to imagine into. That's why music back then was endlessly creative and truly original as a whole. You can still locate amazing contemporary musical artists but their not part of the above ground musical landscape that you had until the mid eighties when "video killed the radio.."
I can add much more about how many amazing70's bands recreated music for the better, reflecting the times, while representing their influences that near, alive and endless.. Post wwII liberty and optimism and respect were still informing the arts maybe until 24hrs news and news cycles began to embittered the masses away from appreciating the sublime, the nuanced personal choices that can unlock the beautiful avenues of discovery..
I could write for hours about the Power of human creative potential. Take risks and exit off the highway of listening to songs that keep you enslaved to a beat instead of moving yourself daily to higher ground. There's miles of open sky above the ten feet or so that gravity keeps us limited to.
