The Demise of Planet X

The album was recorded at Sleaford Mods' regular studio JT Soar in Nottingham, with additional recording done at Abbey Road Studios in London and Invada Studios in Bristol.^[3]

Sleaford Mods had previously used the title "The Demise of Planet X" as the name of a livestream event in early 2021 at the Village Underground in London, when they were in the midst of a tour shortly before releasing the album Spare Ribs.^[4] The name is in reference to the Planet X conspiracy theory, which posits a doomsday scenario resulting from a planetary collision or near-collision. Frontman Jason Williamson told The Standard that although he believes that it is just a conspiracy, "it's like it's already happened. We've already been laid to waste. Now what have we got? Much is the same. Artisan Scotch eggs are still being baked, Pret's still open, but everyone’s on tenterhooks." This idea formed the broad concept for the album.^[5]

On 16 September 2025, Sleaford Mods released a single entitled "Megaton", which at that point had not been publicly attached to an upcoming album. The accompanying music video directed by Nick Waplington shows the duo performing the song at Speakers' Corner in Hyde Park, London. Proceeds from the single went to the charity organisation War Child.^[6] The second single "The Good Life" was accompanied with a Ben Wheatley-directed music video and the announcement for the album on 21 October 2025.^[2] Consisting of a "minimalist, three note beat", the song features vocals from actress Gwendoline Christie—her musical debut—and duo Big Special.^[7] An alternate "dark" version of the music video was later released on Halloween 2025 and, like the original, was directed by Wheatley and shot in one take.^[8]

A third single, "Bad Santa", was released on 20 November 2025 with a video that shows the duo performing the song live at JT Soar,^[9] directed by Ian Tatham.^[10] On 16 December, Sleaford Mods released the single "No Touch", featuring vocals from Sue Tompkins, formerly of Life Without Buildings. She finished her part in two days with the duo while they were recording in Bristol. In a press release, Williamson said that Tompkins had a cold at the time, but they felt "it added to the track." The corresponding music video for the single was directed by Andrea Arnold, an English filmmaker known for works such as Fish Tank (2009) and American Honey (2016).^[11] On 12 January 2026, four days before the release of the album, the duo revealed the fifth single "Elitest G.O.A.T" featuring New Zealand singer-songwriter Aldous Harding with a music video directed by John Minton.^[12]

In a four star review, Andrew Trendell of the NME called the album "the band's most musically ambitious and diverse record yet" and said that the duo "remain just as singular and uncompromising".^[25] In an 8 out of 10 review for Uncut magazine, Stuart Stubbs said that, "with plenty of gags and even more appalling language", The Demise of Planet X "sounds very Sleaford Mods", adding that "The softer edges and new accessibility only makes the fury and dread eerily heavier."^[24] Editors at AllMusic gave the album 4 stars of 5, with reviewer Heather Phares commenting on its political backdrop: "Sleaford Mods may not offer any easy answers, but musically at least, they're more committed to progress than the society around them."^[26] In a mixed review for DIY, Cameron Sinclair Harris thought the album was "most compelling" when it was Williamson's lyrics were more confessional, like on the closer "The Unwrap"; otherwise, they thought that unless the listener is already a fan of the duo, it doesn't provide anything new "beside a few more timely references".^[19]
