What was the best year for prog?

Who the heck told you that? What is your source (re no good synths before mid 74)? Also, I think there's plenty of great sounding albums by the late 70s. I would say by the early 70s it got better (not late). Also, one of the best sounding albums ever made came out in the 60s. Can you guess which one?

It's 1972 for me all the way, the reasons:

Yes - Close to the Edge

Jethro Tull - TAAB

Tangerine Dream - Zeit

Genesis - Foxtrot

Aphrodite's Child - 666

ELP - Trilogy
