According to Tropical Fuck Storm bassist Fiona Kitschin, King Gizzard and the Lizard Wizard were recording their fourteenth studio album, Fishing for Fishies at a house the band owned.

King Gizzard would use the jam as a basis for their 2022 song "The Dripping Tap", while Tropical Fuck Storm turned it into Satanic Slumber Party.

[4] According to the Bandcamp description, the fictional background for the EP is:"Somewhere along a frayed thread of time, a King Gizz and a Tropical Fuck Storm convened under the cloak of night for a slumber party of the satanic persuasion…Pumped full of booze and adrenaline, two of psych-rock’s most powerful joined forces for a 20-minute “Hatjam” chockfull of sax skronks, brick-heavy distortion, and punchy riffs.

"[5]Fiona Kitschin has described the EP as “four guitars, three drummers, two synths, bass, harmonica, electronic sax and lots of singers and silliness.

It’s like ‘Love Shack’ by the B-52’s except it’s evil.”[6] All tracks are written by Tropical Fuck Storm, Stu Mackenzie, Ambrose Kenny-Smith, Joey Walker, Cook Craig, Michael CavanaghMusicians Performed by Tropical Fuck Storm and King Gizzard & the Lizard Wizard Technical Design
