Yeah. King Crimson, Yes, Donnie Osmond they are all the same.
I rather enjoy ELP in their "classical" mode.

The part of the 70s I hated. Castrada singing with new age instruments (is that a theramin?)

ELP, ELO, never cared for them. Never cared for those ‘college’ bands either like Doobie and Steely Dan.

In the decade of the 70s, for me it was:

Zeppelin Stones Who. The Band, Cream,Creedence, ZZ (and a bunch of other southern rock like skynard and Allmans), heck even the Dead played bluesy. Aerosmith, (the Beatles though they were gone but not forgotten in The 70s).
