The lyrics to Xanadu are taken from the poem “Kubla Khan” by Samuel Taylor Coleridge.
According to Coleridge, the poem came to him in a dream after reading about the summer palace of the Mongol ruler Kublai Khan and then taking opium.
It’s a very trippy poem and a very trippy song. The theme of the song is a paradise similar to Eden where the protagonist can “taste anew the fruits of life/the last immortal man” and “dine on honeydew/and drink the milk of paradise.”
The song doesn’t talk of a community or of other people but it can be inferred that one of the utopian themes of this song is ecology: beautiful, rich, fertile nature unspoiled by the touch of mortal man.
In this paradise he will become immortal. However, when the protagonist finds it, he is the only one there. While the utopia doesn’t exactly become a dystopia, (Can you have a dystopia that consists of one person?) it becomes a nightmare because the protagonist “taste my bitter triumph/ as a mad immortal man/nevermore shall I return/Escape these caves of ice”
In Eden there were two people, Adam and Eve and it was paradise because they were immortal together. In “Xanadu” by Rush the person has gone mad because he is an immortal man all alone.
This songs talks about the quest for utopia and a mythical promised land where people become immortal and the dangers of being the only one who finds it.
Utopias are meant to be a communities and you can’t have a community of one.
