Post-rock is a subgenre of experimental rock that emphasizes texture, atmosphere, and non-traditional song structures over conventional rock techniques. Post-rock artists often combine rock instrumentation and rock stylings with electronics and digital production as a means of enabling the exploration of textures, timbres and different styles. Vocals, when present, are often used as an instrumental layer, with many bands opting for entirely instrumental compositions. The genre began in indie and underground music scenes, but deviated.
The term post-rock was coined by music journalist Simon Reynolds and popularized in his review of Bark Psychosis' 1994 album Hex. He later expanded the concept as music "using rock instrumentation for non-rock purposes". The term has since developed to refer to bands oriented around dramatic and suspense-driven instrumental rock, making the term controversial among listeners and artists alike.
