Polygondwanaland (/ˈpɒliɡɒndˌwɑːnəlænd/) is the twelfth studio album by Australian psychedelic rock band King Gizzard & the Lizard Wizard.

[citation needed] The track "Crumbling Castle," which appeared on the demo, was performed live by the band as early as September 2016, albeit in a much shorter form.

Both the track and the music video were finally released on 19 October 2017,[6] exactly one year after the first performance of the song was uploaded to YouTube[citation needed].

"[15] Cultural theorist Benjamin Kirbach argues that, like Murder of the Universe (which also came out in 2017), the narrative of Polygondwanaland "adheres to a similarly mythopoetic three-act structure in which civilization is threatened by ecological calamity."

According to Kirbach: The ensuing political strife results in a failed coup, the mutilated survivors of which ("Having had his eyes gouged / He left without the gift of sight") cybernetically enhance themselves and ultimately regain power by colonizing the world of/as information.

The new supercontinent, polygondwanaland itself, is the terra incognita of digital information systems ("My body’s not a temple / It is a vessel / And a blank slate / An empty hard-drive"), and once human beings enter into it, they're able to see beyond the normal three-dimensions via a new "tetrachromatic" hodography of user-generated data ("Many fingers, many minds and / Many eyeballs puppet my feet").

On the vinyl record, the needle then enters a locked groove, "Hello" repeating in an endless mechanical loop lest a human hand reach in to stop it.
