The Downward Spiral is the second studio album by American industrial rock band Nine Inch Nails, released on March 8, 1994, by Nothing Records and Interscope Records in the United States and by Island Records in Europe.
 It is a concept album detailing the destruction of a man from the beginning of his "downward spiral" to his attempt at suicide.
 "The Downward Spiral" features elements of industrial rock, techno and heavy metal music, in contrast to the band's synthpop-influenced debut album "Pretty Hate Machine" (1989), and was produced by Nine Inch Nails frontman Trent Reznor and Flood.
The Spinal Cord Perception is the first novel by Joshua S. Porter, better known by his stage name Josh Dies, the singer/songwriter for the band Showbread.
 Self-published by Porter in 2006, the book revolves around a small-town substitute teacher named David Rivers, who is haunted by a small black monster which he refers to as the "Llapasllaly".
 Written in a stream of consciousness narrative, the story is told in a series of bi-polar rants by Rivers, and chronicles his thoughts in non-linear sequences from childhood through his adult life.
 It depicts his downward spiral into depression, apathy and an apparent anti-social personality disorder.
 The novel depicts many hallucinations from Rivers' perspective, and the reader is left not knowing which scenes are reality and which are fantasy.
Danny Hyde is an experimental musician and remix artist.
 Hyde has contributed to production and mixing on many Coil albums, including "Horse Rotorvator", "Love's Secret Domain", "The Remote Viewer", "Black Antlers", and "The New Backwards".
 Hyde has also worked with Psychic TV and Pop Will Eat Itself.
 Hyde participated in the creation of many remixes while working with Coil, including several for Nine Inch Nails that were released on "Fixed", "Closer To God" and certified gold release "Further Down the Spiral" as well as the rerelease of quadruple-platinum album "The Downward Spiral".
 His remix of Nine Inch Nails' song "Closer" was featured in the film "Seven".
Further Down the Spiral is the first remix album by American industrial rock band Nine Inch Nails, released on June 1, 1995.
 It is the companion remix disc to "The Downward Spiral".
 The album contains two editions, one denoted as "Halo 10" (released in the United States and in the United Kingdom on the morning of release, to be pulled and replaced with "Halo 10 V2" by lunch time) the other as "Halo 10 V2" (released in Japan, Australia, and the UK), each containing a different set of tracks with a large degree of overlap between the two.
"The Thin White Line" is the first episode of the third season of the animated comedy series "Family Guy".
 This episode was originally produced for season 2.
 It originally aired on Fox in the United States on July 11, 2001.
 The episode features Brian after he joins the police force to sniff out drugs, but eventually becomes addicted to hard drugs, and soon finds himself in a downward spiral after attempting to confront his newfound drug addiction.
 The episode is notable for being "Family Guy"' s first two-part episode, the other part being "Brian Does Hollywood" which aired the following week.
Broken is the debut EP and major-label debut by American industrial rock band Nine Inch Nails, released on September 22, 1992 by Nothing Records, TVT Records, Interscope Records, and Atlantic Records.
 It is the band's second release following their debut studio album, "Pretty Hate Machine" (1989), and consists entirely of new material.
 Produced by frontman Trent Reznor and Flood, it replaces the synthpop style of "Pretty Hate Machine" with a considerably heavier sound that would act as a precursor for Nine Inch Nails' acclaimed second studio album, "The Downward Spiral" (1994).
Gary Talpas is an American art director and photographer.
 Talpas worked as designer and art director for Nine Inch Nails on "Pretty Hate Machine", "Head Like A Hole", "The Downward Spiral" and "Further Down the Spiral".
 He also played keyboards for several early shows during the Pretty Hate Machine tour after Chris Vrenna switched to drums.
Voyage in the Dark was written in 1934 by Jean Rhys.
 It tells of the semi-tragic descent of its young protagonist Anna Morgan, who is moved from her Caribbean home to England by an uncaring stepmother, after the death of her father.
 Once she leaves school, and she is cut off financially by the stepmother, Hester, Anna tries to support herself as a chorus girl, then becomes involved with an older man named Walter who supports her financially.
 When he leaves her, she begins a downward spiral.
 Like William Faulkner's "The Wild Palms", the novel features a botched illegal abortion.
 Rhys' original version of ""Voyage in the Dark" ended with Anna dying from this abortion (see Bonnie Kime Scott's "The Gender of Modernism" for the original ending), but she revised it before publication to the more ambivalent and modernist ending in which Anna survives to return to her now-shattered life "all over again."
 The novel is rich in Caribbean folklore and tradition and post-colonial identity politics, including black self-identification by its white protagonist.
