[11] The genre reflects a preoccupation with outmoded analog technology and bombastic representations of synthetic elements from these epochs of pop culture, with its creators informed by collective memory as well as their personal histories.
He observed that their music drew from "the collective unconscious of late 1980s and early 1990s popular culture" while being "indebted stylistically to various traditions of experimentalism such as noise, drone, repetition, and improvisation.
[19] The emergence of Ariel Pink's Haunted Graffiti, in particular, prompted journalistic discussion of the philosophical concept of hauntology,[20] most prominently among the writers Simon Reynolds and Mark Fisher.
Trainer disagreed with Reynolds' assertion and said the style "arguably" emerged from numerous simultaneous scenes inhabited by artists working in a diverse form of "post-noise neo-psychedelia".
[9] Ariel Pink gained recognition in the mid-2000s through a string of self-produced albums, pioneering a sound that Reynolds called "'70s radio-rock and '80s new wave as if heard through a defective transistor radio, glimmers of melody flickering in and out of the fog".
[11] From 2009 to 2010, Ferraro's music evolved to be increasingly rhythmic and melodic, as Trainer describes, "an oversaturated sonic palette of cheesy pop reminiscent of early video game soundtracks and 1980s Saturday morning cartoons.
[14] Keenan applied the label to a developing trend of 2000s lo-fi and post-noise music in which artists engaged with elements of cultural nostalgia, childhood memory, and outdated recording technology.
Ouspensky, Keenan employed the term "hypnagogic" as referring to the psychological state "between waking and sleeping, liminal zones where mis-hearings and hallucinations feed into the formation of dreams.
"[11] The term reportedly originated with a comment by James Ferraro about the notion that 1980s sounds had seeped into the unconscious of contemporary musicians while they were toddlers falling asleep and their parents played music in another room.
[38][page needed] Among the artists discussed in Keenan's article were Ariel Pink, Daniel Lopatin, the Skaters, the Savage Young Taterbug, Gary War, Zola Jesus, Ducktails, Emeralds, and Pocahaunted.
[11][nb 4] According to Keenan, these artists drew on cultural sources subconsciously remembered from their 1980s and early 1990s adolescence while freeing them from their historical contexts and "hom[ing] in on the futuristic signifiers" of the period.
[15] By 2010, albums by Ariel Pink and Neon Indian were regularly hailed by publications like Pitchfork and The Wire, with "hypnagogic pop", "chillwave", and "glo-fi" employed to describe the evolving sounds of such artists, a number of which had songs of considerable success within independent music circles.
[36] Stereogum's Miles Bowe summarized vaporwave as a combination of "the chopped and screwed plunderphonics of Dan Lopatin ... with the nihilistic easy-listening of James Ferraro’s Muzak-hellscapes on [the 2011 album] Far Side Virtual".
"[50] According to Harper, vaporwave and hypnagogic pop share an affinity for "trash music", both are "dreamy" and "chirpy", and both "manipulate their material to defamiliarise it and give it a sense of the uncanny, such as slowing it down and/or lowering the pitch, making it, as the term goes, ‘screwed’.
[50] David Keenan's original Wire article incited a slew of hate mail that derided the "hypnagogic pop" label as the "worst genre created by a journalist".
[54] In the 2010 Rewind issue of The Wire, Keenan said that h-pop had "migrated from a process designed to liberate desire from marketing formulas to a carrot in the mouth of a corpse that has proved irresistible to underground musicians looking for an easy route to mainstream acceptance.
"[39][nb 6] He invoked chillwave as "one of the more meaningless sobriquets applied to the new future pop visions" and "a much more appropriate description of the mindless, depoliticised embracing of mainstream values that H-pop has come to be associated with.
[5][nb 7] The Guardian's Dorian Lynskey called the hypnagogic tag "pretentious",[58] while New York Times writer Jon Pareles criticized the style as "annoyingly noncommittal music".
[5] Altered Zones contributor Emilie Friedlander prophesied in 2011 that Ariel Pink, John Maus, James Ferraro, Charles Free, Spencer Clark, and R. Stevie Moore would be remembered as musicians who "elevated the crackle and grain of low-fidelity recording ... and made the vocabulary of pop music and the preoccupations of the avant-garde seem a lot less incompatible than much of the previous century had implied.
[53] In a 2012 interview, Pink acknowledged that he was aware that he "was doing something that sounded like the trace of a memory you can't place" and argued that such evocations had become so ingrained into modern music that "people take it for granted".
[18] Adam Harper noted among hypnagogic pop artists a tendency "to turn trash, something shallow and determinedly throwaway, into something sacred or mystical" and to "manipulate their material to defamiliarise it and give it a sense of the uncanny.
