RE: Rock and Roll as the Poetry of Our Time--a work in progress
There is a lot of rich history just with the subterraneans. But, moving on ....
You've got Jimi Hendrix, All Along the Watchtower (which Dylan wrote), Janice Joplin's Mercedes Benz or Me and Bobby McGee (which has been covered by almost everybody, but no one does it as well), and American Pie by Don McLean, the meaning of which has been the subject of debate since recorded.
In the '70s, rock music splintered so many different ways. There was heavy metal, southern rock, soft rock, hard rock, disco, jazz fusion, punk rock, glam rock, progressive rock, new wave, and blues rock - the god of which would be Eric Clapton going all the way back to The Yardbirds. You could put the Clap in almost any category and he rules them all.
So much to tell, so little time. :-)
