Recorded based on jam sessions, the album sees the band incorporating a heavy metal style.

Lead vocalist Stu Mackenzie stated that the album's concept is "about humankind, and it's about planet Earth, but it's also about witches and dragons, and shit.

Later that month, on March 12, 2023, they posted a video on their social media with the caption "New album locked and JOEDED," featuring a clip from what was presumed to be a new song.

[6] On May 7, 2023, they announced the album and artwork, which was described by the band as "a vivid, fiery painting of a lizard-like monster in an industrial, apocalyptic landscape.

I mixed 3D animation, modeling & live footage in a 3D video game program to create this marvelous voyage of man & beast.

"[14]The album also contains a 14-minute bonus track, "Dawn of Eternal Night," featuring Leah Senior, available exclusively on vinyl.

[12] The style of Senior's calm narration over background sounds performed by the band is reminiscent of the interludes featured in the group's earlier album, Murder of the Universe.

[23] A four-out-of-five-star review in AllMusic commended the performances, compositions, and lyrical themes on the album, concluding: "The stricter members of the metal community might see King Gizzard as interlopers with no real metal cred, but after Rats Nest and now this thrillingly massive album, there's no reason the band shouldn't be considered one of the best practitioners of the genre around.
