The longest part of Satanic Slumber Party is “Satanic Slumber Party Part 3 (Hoof And Horn)” It’s a twelve-minute long musique concrète piece that blends elements of the ‘Hat Jam’ sessions between Tropical Fuck Storm and King Gizzard recorded in 2018. While the song is mostly original, there are a few parts taken from the jam. The echoey synths at the beginning of “Hoof And Horn” can be found in the third demo of “The Dripping Tap” (released on Demos Vol. 5: Music To Think Existentially To) alongside drumming from either the second or third demo. The end of “Hoof And Horn” features a segment from the second demo found on Demos Vol.4: Music To Die To. The track was released as the third track on Satanic Slumber Party on March 14th, 2022, and was later included on Hat Jam on April 11th, 2022.
