After the album was released, a [[bootlegs|bootleg]] called ''[[Purest Feeling (album)|Purest Feeling]]'' surfaced. It contains early recordings of most of the tracks found on the album (including an early version of "Ringfinger" entitled "Twist"), as well as a couple that were not used ("[[Purest Feeling (song)|Purest Feeling]]" and "[[Maybe Just Once]]"). Demos that were likely sent to record labels also exist: one batch ("Down In It", "Sanctified", "Kinda I Want To", and "Twist") can be found on the ''[[Demos & Remixes]]'' bootleg, and another batch ("Sin", "Terrible Lie", "Sanctified", "Twist", and "Down In It") are on an uncirculated cassette, one copy of which is privately owned by [[Martin Atkins]].[https://exclaim.ca/music/article/early_demo_of_nine_inch_nails_pretty_hate_machine_hits_ebay] The demos on the Atkins tape may be from the same batch as those on ''Demos & Remixes''.
''Pretty Hate Machine'' was recorded in various studios around the world with Reznor collaborating with some of his most idolized producers - [[Flood]] at Syncro Sound in Boston, Keith LeBlanc at Unique Recording Studios in New York, [[Adrian Sherwood]] at Roundhouse Studios in London, and John Fryer at Blackwing Studios in London. Flood was originally supposed to produce the entire album, but couldn't because of his prior commitment with Depeche Mode.[https://www.theninhotline.com/archives/articles/display/530] Reznor used his own journal entries as sources and inspiration for the album's lyrics.[https://www.theguardian.com/music/2018/jun/21/trent-reznor-nine-inch-nails-youre-seeing-the-fall-of-america] He also listened extensively to [[Gary Numan]]'s album ''Telekon'' while recording the album.[https://www.electronicbeats.net/mr-style-icon-gary-numan-on-trent-reznor/]
After the album was finished, TVT Records were not happy about the direction the album had taken from the original demos. This would lead to friction between Reznor and the label. John Fryer elaborated:
