You Forgot "Tarkus" people!
Definitely one of ELP best works.
Released on 1971 if you didn't know.
as For King Crimson, I like their first 4 albums.
I Definitely don't recommend borrowing KC albums cause you tend to discover them slowly.
I've Never heard of a Serious Progressive Rock fan who didn't like the "In the court..." album.
most of the people who like progressive rock like either the court through Island era of KC(1969-1971, IN The Court of the crimson king, In the wake of poseidon, Lizard, Islands), Or the Red era (1972-1974, Lark's Tongue in Aspic, Starless and Bible Black, Red).
Cheers Guys...
