Purity

This song is based on a story Slipknot lead singer Corey Taylor discovered on a website called Crime Scene about Adrianne Purity Knight, a 20-year-old college student who was stalked by a former boyfriend who buried her in a homemade wooden coffin where she died. According to the story, she was confined during the day in a small box no bigger than a coffin for six years, and became conditioned with Stockholm Syndrome, which occurs when a person finally gives themselves willingly to their captor and believes they are in love with them, or at least understands and accepts their captivity without resistance. It was only after the song was released that Taylor found out the story wasn't true. The website he was reading posts fictional murder-mysteries that readers can try to solve. By this time he had talked about how the story inspired the song, which led to a lawsuit. The song ended up being pulled from the album.

"Purity" was included on Slipknot's 1999 self-titled album, their first on a major label. The album established them as innovators in hardcore and paved the way for their success in the 2000s.

After this song led to legal action, Corey Taylor explained that the title came from the website but the story was inspired by the "woman in a box" films The Collector and Boxing Helena. The Collector inspired another song in the album, "Prosthetics."
