Post-Rock is a very hard-to-define genre. Generally, it's a style that needs to be heard to understand. While the genre might be associated with long compositions with crescendos, many post-rock bands, especially from the "first wave" write relatively short songs. Most commonly defined as a band that uses traditional rock instruments to play non-traditional rock music, whether it be modern classical, ambient, noise, or so on, though there are occasional exceptions

PostRock has a very confusing history. Some people credit the Music/VelvetUnderground for starting it with songs like "Heroin" which [[BoleroEffect started off extremely quiet and ended in droney, massive climax]]. Other sources give credit to the "{{Krautrock}}" movement of TheSixties and TheSeventies. Another possible UrExample is Music/KingCrimson's slowly unfolding song "Starless", which contains a lengthy, BoleroEffect-laden instrumental passage typical of the genre, while others point to the works of Music/PublicImageLtd. All sources seem to agree that the movement "officially" started either in 1991, when Music/{{Slint}} released their album ''Music/{{Spiderland}}'' and Music/TalkTalk released ''Music/LaughingStock'', or in 1988, when Talk Talk relased ''Spirit of Eden''. All three albums are considered classics and are extremely influential. The term "post-rock" itself is generally considered to have been introduced as a descriptor for music of this genre in a review of Bark Psychosis' 1994 album ''Hex'' by music journalist Simon Reynolds which appeared in ''Mojo'' in March of that year, although Reynolds claims to have used the term before that review. [[note]]He also did not invent it, although he thought he did at the time, but his use of the term does appear to have been the first time it was used to describe this particular genre of music.[[/note]] Reynolds [[http://web.archive.org/web/20011202075606/http://www.thewire.co.uk/out/1297_4.htm clarified]] the term in an article for ''The Wire'' published later that year, describing it as music "using rock instrumentation for non-rock purposes, using guitars as facilitators of timbre and textures rather than riffs and power chords."

For the first few years many music enthusiasts had trouble differentiating this and the genre of {{Slowcore}}. This is because Music/{{Slint}} were heavily influenced by Music/{{Codeine}}, often considered the first Slowcore band. For a while the droney sounds from the two got many Slowcore bands mislabeled as PostRock and vice versa. Another genre which PostRock is often confused with (and, indeed, does overlap with in some cases) is SpaceRock, which was an influence on it, but which has a somewhat different (read: [[ThisIsYourPremiseOnDrugs drug-oriented]]) focus.

Throughout the TheNineties bands such as Cul de Sac, Tortoise, Labradford, Bowery Electric and Stars of the Lid helped mold the genre into what it resembles now. The movement sparked mainly from three different cities with their own separate scenes: Chicago, Glasgow, and Montreal.

Then, in the late 1990s and 2000s bands such as Music/{{Mogwai}}, Music/GodspeedYouBlackEmperor, and Music/ExplosionsInTheSky helped expand the genre even more. Around the same time, a number of SludgeMetal bands started picking up on the genre, resulting in "post-metal" or "atmospheric sludge". (Post-metal has actually been around since at least 1992, with Music/{{Neurosis}}'s [[TropeMaker trope-making effort]] ''Souls at Zero'', but experienced an explosion in popularity during the 2000s with releases like Music/{{Isis}}' ''Oceanic'' and ''Panopticon'' and Music/CultOfLuna's ''Salvation'' and ''Somewhere Along the Highway''). The genre has even been combined with BlackMetal, resulting in fusions like the works of Music/{{Alcest}} and Music/{{Deafheaven}} (whose 2013 effort ''Music/{{Sunbather}}'' became the most favourably reviewed album ''of any genre'' that year). Needless to say, the underground is now littered with PostRock bands.

The "big 4" of post rock are, generally, considered to be Music/ExplosionsInTheSky, Music/SigurRos, Music/GodspeedYouBlackEmperor, and Music/{{Mogwai}}.

!!Tropes common in the genre
* BoleroEffect: While this wasn't universally common among post-rock bands when the [[EarlyInstallmentWeirdness genre was in its infancy]], it's nowadays considered one of the most noteworthy characteristics of the genre.
* DarkerAndEdgier: Post-metal is essentially DarkerAndEdgier post-rock. Similarly, BlackMetal/post-rock fusions tend to be DarkerAndEdgier post-metal (though they also tend to be LighterAndSofter when compared to most other black metal acts).
* EpicRocking: It's difficult to find a post-rock band that hasn't used this at least once. Twenty-minute-plus songs are a staple of the genre.
* {{Instrumentals}}: Many bands do not use vocals. In fact, instrumental groups are probably more common in the genre than vocal groups.
* LimitedLyricsSong: Even if there are lyrics, they probably won't take up much of the song, or be particularly wordy. The ultimate example of this is Music/SigurRos' album ''( )'', whose eight songs all contain the exact same nonsense line as the only lyrics on the entire album.
* MainstreamObscurity: Some of the bands are fairly well-known, but due to the length of their songs, they rarely get played on the radio.
* MetalScream: Extremely common in post-metal, and not entirely unheard of in post-rock either (Music/{{Slint}} probably started it out with the ''epic'' screams at the end of "Good Morning, Captain").
* NeoclassicalPunkZydecoRockabilly: Like many other genres, post-rock started out as an example of this trope, and it's still extremely common for bands in the genre to use it even now that the genre is itself an established style. Many of its subgenres such as post-metal also started out as examples of this trope.
* NoHitWonder: Again, while many bands have received a fair amount of commercial success, hit singles aren't really the province of the genre.
* {{Sampling}} and SpokenWordInMusic: Perhaps due to the influence of Music/GodspeedYouBlackEmperor and Music/{{Swans}}, these are frequent characteristics of post-rock music, as well as music influenced by the genre. Music/{{Slint}} also did a lot of the latter trope.
* SpiritualSuccessor: The genre is sometimes considered this to ProgressiveRock and {{Krautrock}}.
* UncommonTime: Again, a characteristic of the genre that can probably be traced back to Music/{{Slint}}, who are also called MathRock for a reason.
