"The Fly" is a song by Irish rock band U2.
 It is the seventh track from their 1991 album, "Achtung Baby", and it was released as the album's first single on 21 October 1991.
 "The Fly" introduced a more abrasive sounding U2, as the song featured danceable hip-hop beats, industrial textures, distorted vocals, and an elaborate guitar solo.
 Lead vocalist Bono described the song as "the sound of four men chopping down "The Joshua Tree"," due to its departure from the traditional sound that had characterised the band in the 1980s.
Hate Forest was a Ukrainian black metal band formed by Roman Saenko, the leading member of Drudkh, Dark Ages, and Blood of Kingu.
 Thurios joined the band in 1998 after the recording of "Scythia".
 The music is mostly very fast, but occasionally slow, with low, distorted vocals and dark ambient elements (some releases have consisted entirely of dark ambient tracks) and musical influences range from Scandinavian black metal to traditional death metal.
 According to the band, its lyrics are about mythology, mainly Slavic, and inspired by H. P. Lovecraft's stories and Friedrich Nietzsche's philosophy.
 The band never gave interviews, never released photos, and held its distance from the black metal scene.
 After Hate Forest disbanded, Saenko focused on Blood of Kingu, a band similar in style but of different inspiration but in 2016, it had also ended.
Easy Action is a Swedish band from Stockholm that was first formed in 1981 by Pelle Almgren (ex-Warhead), Henrik "2 meter" Jermsten (ex-Stoodes), Bosse Belsen (aka Zinny J. Zan of Shotgun Messiah/Kingpin/Zan Clan - drums) and Björne Fröberg (bass, ex-Warhead).
 Bosse and Björne quit and were replaced by Ola "Skox" Andersson and drummer Urban "Ubbe" Sundbaum (ex-Lustans Lakejer).
 Stranded Records became interested and released the single "Honcho Bongo".
 It didn't sell well and when the second single, "Om jag vore kung", also failed the band split up.
 Skox and 2 meter formed Psyhedelic Mongo and Pelle Almgren started writing songs instead.
 Easy Action was reformed as a glam metal band in 1982 by Kee Marcello and Alex Tyrone (aka Peo Thyrén).
 The two played together in the Swedish glam act Noice when they decided to start the ultimate glam rock band, mixing their influences of 1970s glam with a punk/metal attitude.
 They met the original singer Bosse Belsen, now named Zinny J. Zan, at the Stockholm rock club Ritz and recorded his vocals on the first demos the very same night.
 Later the Noice drummer Fredrik Von Gerber and the guitar player Danny Wilde joined the band.
 In 1983 they got signed to the US major label Sire and became the first Swedish band ever to sign a worldwide record deal.
Industrial metal is the fusion of heavy metal music and industrial music, typically employing repeating metal guitar riffs, sampling, synthesizer or sequencer lines, and distorted vocals.
 Founding industrial metal acts include Ministry, Godflesh, KMFDM, and Rammstein.
"Stigmata" is a song by industrial metal band Ministry, released as a single from their 1988 album "The Land of Rape and Honey".
 The song features distorted vocals, guitars and compressed drum machine loops.
 The song was an underground hit.
 The video features gritty black and white, strobe-like montages of eyes, machinery, gears, symbols, the band playing live, Paul Barker on a motorcycle, and what appear to be neo-Nazi skinheads.
 The song was said to be "Ministry's finest moment until 1992".
A hallucination is a perception in the absence of external stimulus that has qualities of real perception.
 Hallucinations are vivid, substantial, and are perceived to be located in external objective space.
 They are distinguishable from these related phenomena: dreaming, which does not involve wakefulness; illusion, which involves distorted or misinterpreted real perception; imagery, which does not mimic real perception and is under voluntary control; and pseudohallucination, which does not mimic real perception, but is not under voluntary control.
 Hallucinations also differ from "delusional perceptions", in which a correctly sensed and interpreted stimulus (i.e., a real perception) is given some additional (and typically absurd) significance.
Dunkelwerk is the name of a German band which describes its sound as "Endzeit Electro" (dark electronic beats and sounds often combined with Nazism themes or horror apocalyptic scenarios and distorted vocals), referring to a genre which was originally established by bands like Wumpscut and Leæther Strip and is nowadays produced by bands like The Retrosic, Suicide Commando or Hocico.
 Dunkelwerk consists of only one person and is a pure studio project, not doing any live performances or any other public events.
 The name of the band is an old German idiom which can be translated as "dark work" or "dark factory".
 The producer behind Dunkelwerk has decided to work under the pseudonym "losttrooper", being restrained to offer pictures of himself.
Raubtier ("German:" predator/animal of prey) is a Swedish Industrial metal band from Haparanda.
 On 25 March 2009 they released their first album "Det finns bara krig" ("There is only war" in English).
A Screw is an EP by the New York City experimental rock group Swans.
 The EP was later reissued as additional tracks to the CD release of "Holy Money".
 The single's title song shows the band diving their farthest into the realm of industrial dance music, complete with dubby, distorted vocals, and complex programmed rhythms, an interesting contrast to the naturalistic album version.
