Rat Wars is the fifth studio album by American noise rock band Health. The album was conceived after the band put together the second Disco4 album remotely. Vocalist and guitarist Jake Duzsik initially considered naming it Outer Dark, after the novel by Cormac McCarthy, but eventually settled on Rat Wars, the title of a track from their previous album Vol. 4: Slaves of Fear; the band compared the situation to The Doors' Waiting for the Sun.
Rat Wars includes the work of a number of guest artists, including synthwave artist Sierra, electronic producer SWARM, Willie Adler of metal band Lamb of God, and members of Youth Code and Street Sects. It was produced by Stint, though for "Children of Sorrow", band member John Famigletti intentionally used the demo mix as he felt it had "more vibe". "Future of Hell" was derived from a track by electronic artist Nexy that Famigletti heard whilst driving; he asked to work with him on the album, but was declined, leading to the track being sampled instead.
Rat Wars incorporates elements of metal, electronic and industrial genres. It continues in the direction established by Health's previous album Vol. 4: Slaves of Fear, being thematically darker and sonically harsher than the band's previous work.
Duzsik described it as more personal than Health's previous work, being thematically "much more of an ‘I’ record than a ‘we’ record” and influenced by his "disharmonious state". He called the imagery of children in the lyrics "Jungian", being influenced by his own experiences raising his son. From: https://en.wikipedia.org/wiki/Rat_Wars
