In reply to kevin stephens:
Not what you asked for, but I have to add that I have childhood memories of being really discomforted by the cover art of my parents' copy of "In the Court of the Crimson King" - I'd flip through their vinyl collection and always get hit with a queasy shudder when I came across it (same with their copy of Neil Young's eponymous album - I find both to have a slightly nightmarish quality)..... I bet I have really horrible dreams tonight!
