Grindcore is an extreme fusion genre of heavy metal and hardcore punk that originated in the mid-1980s, drawing inspiration from abrasive-sounding musical styles, such as thrashcore, crust punk, hardcore punk, extreme metal, and industrial. Grindcore is considered a more noise-filled style of hardcore punk while using hardcore's trademark characteristics such as heavily distorted, down-tuned guitars, grinding overdriven bass, high-speed tempo, blast beats, and vocals which consist of growls, shouts and high-pitched shrieks. Early groups like Napalm Death are credited with laying the groundwork for the style. It is most prevalent today in North America and Europe, with popular contributors such as Brutal Truth and Nasum. Lyrical themes range from a primary focus on social and political concerns, to gory subject matter and black humor.
Anarcho-punk is an ideological subgenre of punk rock that promotes anarchism. Some use the term broadly to refer to any punk music with anarchist lyrical content, which may figure in crust punk, hardcore punk, folk punk, and other styles.
Deathrock is a rock music subgenre incorporating horror elements and gothic theatrics. It emerged from punk rock on the West Coast of the United States in the early 1980s and overlaps with the gothic rock and horror punk genres. Notable deathrock acts include Christian Death, Kommunity FK, 45 Grave, and Super Heroines.
Skate punk is a skater subculture and punk rock subgenre that developed in the 1980s. Originally a form of hardcore punk that had been closely associated with skate culture, skate punk evolved into a more melodic genre of punk rock in the 1990s similar to pop punk. Since then, it has predominately featured fast tempos, lead guitar playing, fast drumming, and singing. Occasionally, skate punk also combines the fast tempos of hardcore punk and melodic hardcore with the catchy hooks of pop-punk.
Horror punk is a music genre that mixes punk rock and 1950s-influenced doo-wop and rockabilly sounds with morbid and violent imagery and lyrics which are often influenced by horror films and science fiction B-movies. The genre was pioneered by the Misfits in the late 1970s and early 1980s. Subsequent bands formed in the Misfits' wake like Mourning Noise, the Undead and Samhain, solidifying horror punk's first wave. In the late 1990s and early 2000s the genre gained attention through the reunion of the Misfits and success of groups like AFI, Son of Sam and the Murderdolls. This popularity continued to the modern day with Blitzkid, Calabrese and Creeper.
A number of heavy metal genres have developed since the emergence of heavy metal during the late 1960s and early 1970s. At times, heavy metal genres may overlap or are difficult to distinguish, but they can be identified by a number of traits. They may differ in terms of instrumentation, tempo, song structure, vocal style, lyrics, guitar playing style, drumming style, and so on.
Popular music of the United Kingdom in the 1970s built upon the new forms of music developed from blues rock towards the end of the 1960s, including folk rock and psychedelic rock movements. Several important and influential subgenres were created in Britain in this period, by pursuing the limitations of rock music, including British folk rock and glam rock, a process that reached its apogee in the development of progressive rock and one of the most enduring subgenres in heavy metal music. Britain also began to be increasingly influenced by third world music, including Jamaican and Indian music, resulting in new music scenes and subgenres. In the middle years of the decade the influence of the pub rock and American punk rock movements led to the British intensification of punk, which swept away much of the existing landscape of popular music, replacing it with much more diverse new wave and post punk bands who mixed different forms of music and influences to dominate rock and pop music into the 1980s.
Popular music of the United Kingdom in the 1980s built on the post-punk and new wave movements, incorporating different sources of inspiration from subgenres and what is now classed as world music in the shape of Jamaican and Indian music. It also explored the consequences of new technology and social change in the electronic music of synthpop. In the early years of the decade, while subgenres like heavy metal music continued to develop separately, there was a considerable crossover between rock and more commercial popular music, with a large number of more "serious" bands, like The Police and UB40, enjoying considerable single chart success.
Crust punk is a subgenre of punk rock influenced by the English punk scene as well as extreme metal. The style, which evolved in the early 1980s in England, often has songs with dark and pessimistic lyrics that linger on political and social ills. The term "crust" was coined by Hellbastard on their 1986 Ripper Crust demo.
American rock has its roots from 1940s and 1950s rock and roll, rhythm and blues, and country music, and also draws from folk music, jazz, blues, and classical music. American rock music was further influenced by the British Invasion of the American pop charts from 1964 and resulted in the development of psychedelic rock.
British rock describes a wide variety of forms of music made in the United Kingdom. Since around 1964, with the "British Invasion" of the United States spearheaded by the Beatles, British rock music has had a considerable impact on the development of American music and rock music across the world.
D-beat is a style of hardcore punk, developed in the early 1980s by imitators of Discharge, after whom the genre is named, as well as a drum beat characteristic of this subgenre. D-beat is known for its "grinding, distorted and brutally political" sound. Discharge may have themselves inherited the beat from Motörhead and the Buzzcocks. D-beat is closely associated with crust punk, which is a heavier, more complex variation. The style was particularly popular in Sweden, and developed there by groups such as Crude SS, Anti Cimex, Mob 47, and Driller Killer. Other D-beat groups include Doom and the Varukers from the UK; Disclose from Japan; Crucifix and Final Conflict from the U.S.; Ratos de Porão from Brazil; and MG15 from Spain. While the style initially developed in the early 1980s, a number of new groups working within the subgenre emerged in the mid-1990s. These include the Swedish groups Wolfbrigade, Totalitär, Avskum, Skitsystem, and Disfear.
Melodic hardcore is a broadly defined subgenre of hardcore punk with a strong emphasis on melody in its guitar work. It generally incorporates fast rhythms, melodic and often distorted guitar riffs, and vocal styles tending towards shouting and screaming. Nevertheless, the genre has been very diverse, with different bands showcasing very different styles. Many pioneering melodic hardcore bands, have proven influential across the spectrum of punk rock, as well as rock music more generally. The term melodic punk is often used to describe both melodic hardcore and skate punk bands.
Street punk is an urban working class-based subgenre of punk rock, which partly emerged as a rebellion against the perceived artistic pretensions of the first wave of British punk. Street punk emerged from the style of Oi! and hardcore punk bands. A key band in defining the aesthetic was the Exploited. Street punks generally have a much more ostentatious and flamboyant appearance than the working class or skinhead image cultivated by many Oi! groups. Street punks commonly sported multi-coloured hair, mohawks, tattoos, heavily studded vests and leather jackets, and clothing, especially plaids, adorned with political slogans, patches, and/or the names of punk bands. In the 1990s and 2000s, a street punk revival began with emerging street punk bands such as the Casualties.
