Context paragraphs:
The Downward Spiral: 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.

Hurt (Nine Inch Nails song): "Hurt" is a song by American industrial rock band Nine Inch Nails from their second studio album, "The Downward Spiral" (1994), written by band leader Trent Reznor.  It was released on April 17, 1995 as a promotional single from the album.  The song received a Grammy Award nomination for Best Rock Song in 1996, but ultimately lost to Alanis Morissette's "You Oughta Know".

Pretty Hate Machine: Pretty Hate Machine is the debut studio album by American industrial rock band Nine Inch Nails, released on October 20, 1989 by TVT Records in the United States, Island Records in Europe and by Interscope Records and Atlantic Records internationally.  The album is compiled of reworked tracks from the band's "Purest Feeling" demo, as well as songs composed after its original recording.  Although it was critically and commercially successful (especially for an independent label), Trent Reznor (Nine Inch Nails' only constant band member) feuded with TVT Records during the album's promotion. " Slant Magazine" placed the album at number 50 on its list of the "Best Albums of the 1980s", commenting, "before attempting suicide in "The Downward Spiral" and living with the wrist scars in "The Fragile", "Pretty Hate Machine" sent out sleek, danceable warning shots".

Gary Talpas: 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.

Mr. Self Destruct: "Mr. Self Destruct" is a song by American industrial rock act Nine Inch Nails.  Written by frontman Trent Reznor, co-produced by Flood and recorded at Le Pig in 1993, it is the opening track of "The Downward Spiral" (1994), and predicts the album's "ugly" aesthetic and mostly "angry" tone.  The song also gives a lyrical background of the album's protagonist.

Danny Hyde: 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 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".

An Omen EP: An Omen EP (stylized as "An omen EP_") was the second extended play release by American post-industrial group How to Destroy Angels, released November 13, 2012.  Produced by Nine Inch Nails frontman Trent Reznor, his wife Mariqueen Maandig and longtime collaborator Atticus Ross, the EP contained various tracks later issued on their 2013 debut album, "Welcome Oblivion".

Broken (EP): 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).
