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. All sources seem to agree that the movement "officially" started either in 1991, when Music/{{Slint}} released their album ''Spiderland'' and Music/TalkTalk released ''Laughing Stock'', 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 awhile the droney sounds from the two got many Slowcore bands mislabeled as PostRock and vice versa.

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 2000's bands such as Mogwai, Music/GodspeedYouBlackEmperor, and Music/ExplosionsInTheSky helped expand the genre even more. Then, a number of SludgeMetal bands started picking up on the genre, resulting in "post-metal" or "atmospheric sludge". Since then, the underground has been littered with PostRock bands.

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

It's worth noting that most of the non-orchestral tracks on the ''Manga/DeathNote'' soundtrack could be considered post-rock. The early works of Music/{{Mono}} seem to have been particularly influential on them.
