Kill City was originally recorded in 1975 after the disintegration of the Stooges. It was to be used as a demo to give to record labels in hopes of getting Pop a new contract. His vocals were recorded on weekends when he received permission to leave a mental hospital he was staying in at the time for treatment of his long-standing heroin addiction.[citation needed]

The original 1975 "demo" mix of the album remains unheard, with the exception of three tracks which have been released on various compilations (including A Million in Prizes: The Anthology and Original Punks): "Johanna", "Consolation Prizes" and "Kill City". These tracks sound markedly different from those on the final version of the album, with different guitar parts and, in the case of "Johanna", no saxophone.
