Satanic Offerings (Demos & B-Sides) is an official collection of demos, alternate versions, and B-sides spanning the recording periods of Koyo Bloom's first three studio albums.

The collection traces the band's evolution from Huw and Jacob demoing songs in their student bedrooms in Leeds while navigating the breakup of their teenage band, A Farewell To Tyrants, and laying the foundations for what would become Koyo Bloom. It follows the songwriting journey through the recordings leading up to the band's sophomore album, includes B-sides from the Gordon Raphael sessions that also produced "Walking On Air", and features a revised version of "Nefertiti", originally intended for Onism.

Revisited and reworked numerous times over the years, "Nefertiti" remained one of the band's longest-running unreleased songs—until now.

These recordings capture ideas in their earliest forms, alternate takes, forgotten favourites, and songs that almost made the final cut, offering a rare glimpse behind the making of Koyo Bloom's first three albums.
