"Purity" and "Frail Limb Nursery" were inspired by a story published online about a girl named Purity Knight, who was kidnapped and buried alive. The website, called
Crime Scene, presents fictional stories as real life crime cases. Originally, the website included no disclaimer saying that it was a work of fiction. Many readers believed the story to be true, including
Corey Taylor: "I still think its real - see the thing whether it's true or not, it's a real story - that we read about - that fucked our whole world up - can you imagine a girl being buried in a box and having all this lecherous bullshit drip down on her from this guy? [...] - it just hurts your head". According to Taylor, the song "was originally called 'Despise' but it didn't work when we tried to put it together… Ross
[Robinson] took it and helped us restructure it." In an interview, Taylor claimed the lyrics had been written five years prior to the song's release, that only the name had been inspired by the Purity Knight story. He also said that inspiration came from films such as
Boxing Helena and
The Collector, and not the story. "Frail Limb Nursery" is the prelude to "Purity", and directly samples the audio used on
Crime Scene. The outro of the track "Tattered & Torn" features the intro to "Frail Limb Nursery" on the later edition of the album, though the latter was never included on any rereleases. == Release and controversy ==
