Mystery City leaves behind disappearing street maps that only update when the band changes a lyric, making songs part of the city's physical architecture.
Related: Mystery City is the location of main character Shrell's home -- a golden underwater paradise -- in the AI Kills album Stillbirth (2025). This is a parallel world vision of another possible Mystery City. The song "Mystery City [BONUS TRACK]" was originally provided as a bonus track when purchasing the album at Bandcamp. When Bandcamp removed all AI Kills music at the end of January 2026, the song became unreleased again for a time, creating yet more mystery around the track.
