The story of "Karn Evil 9" is told in three parts, with the second part being an instrumental interlude. First Impression, Part 1 begins with a tale of a bleak world (although timeframe is not specified): "Cold and misty morning I heard a warning borne on the air ..." and where humanity is either being destroyed or has fallen into decay and helplessness. First Impression, Part 2 tells how the decadence of the old world is preserved through exhibits that are part of a futuristic carnival show, which exhibits depravities like "seven virgins and a mule", along with things that are rare in the future, such as a "real blade of grass".
