get the picture? not a single use of the term "classic" to generalize a genre. Obviously large diversion in the hard rock bands with many crossing over to more progressive leanings because being a hardrock musician was progressive in itself, they also played their share of their versions of the blues and brought in various folk, country flavors, even funk as well, once again because they were hardrockers they were more open to experiment and play with things than worry about radio hits or pleasing narrow minded fans.
Then even bands like in my "rock" listing showed country flavor relative to their topographical origions.
Or the Chicago sounding rock of bands like Chicago, Blood Sweat and Tears mixing Chicago blues and jazz influences with rock
Or midwest country flavored rockers like Head East and other names that excape me now
it really pisses me off that in the times of kids that just cant come up with enough sub genres to classify their music in want to sum up the late 60's and 70's as "classic rock". When the truth is most of these bands were a genre in themselves, sounding nothing alike, being truely creative with no one else to follow,clone,or copy, the real ground breakers being tossed into one big bucket of shit as if they had everything in common. Todays bands in given genres are stale by comparision to the early bands that simply had their hands on their asses and went for it, whatever came out they made something of it, even if it was totally different than the last song they worked on.
