King Crimson albums you'll like -- "Larks Tongues In Aspic", "Starless and Bible Black", and "Red" for sure. If you get those and like them, then "Islands" would be the next step, then "In The Court of the Crimson King", their debut. I don't see you liking "Lizard" at all, and "In The Wake of Poseidon" is fairly iffy. And the re-formed Crimson stuff from the '80s, too much like math-rock. I'm gonna guess that the one you bought and didn't like was one of the ones like "Discipline", "Three of a Perfect Pair", "Thrak" or "Thrak Attack".
Now, if you're really brave, check out some Gentle Giant...
