Extreme metalExtreme metal is a loosely defined umbrella term for a number of related heavy metal music subgenres that have developed since the early 1980s. It has been defined as a "cluster of metal subgenres characterized by sonic, verbal, and visual transgression". The term usually refers to a more abrasive, harsher, underground, non-commercialized style associated with the speed metal, thrash metal, black metal, death metal, and doom metal genres.
Black metalBlack metal is an extreme subgenre of heavy metal music. Common traits include fast tempos, a shrieking vocal style, heavily distorted guitars played with tremolo picking, raw (lo-fi) recording, unconventional song structures, and an emphasis on atmosphere. Artists often appear in corpse paint and adopt pseudonyms. During the 1980s, several thrash metal and death metal bands formed a prototype for black metal. This "first wave" included bands such as Venom, Bathory, Mercyful Fate, Hellhammer and Celtic Frost.
Death metalDeath metal is an extreme subgenre of heavy metal music. It typically employs heavily distorted and low-tuned guitars, played with techniques such as palm muting and tremolo picking; deep growling vocals; aggressive, powerful drumming, featuring double kick and blast beat techniques; minor keys or atonality; abrupt tempo, key, and time signature changes; and chromatic chord progressions. The lyrical themes of death metal may include slasher film-style violence, political conflict, religion, nature, philosophy, true crime and science fiction.
SlayerSlayer was an American thrash metal band from Huntington Park, California formed in 1981 by guitarists Kerry King and Jeff Hanneman, drummer Dave Lombardo and bassist/vocalist Tom Araya. Slayer's fast and aggressive musical style made them one of the "big four" bands of thrash metal, alongside Metallica, Megadeth, and Anthrax. Slayer's final lineup comprised Araya, King, drummer Paul Bostaph (who replaced Lombardo in 1992 and again in 2013) and guitarist Gary Holt (who replaced Hanneman in 2013).
SatanismSatanism is a group of ideological and philosophical beliefs based on Satan. Although several historical precedents exist, the contemporary religious practice of Satanism began with the founding of the atheistic Church of Satan by Anton LaVey in the United States in 1966. Prior to that time, Satanism existed primarily as the subject of accusations by various Christian groups toward perceived ideological opponents rather than a self-identity or expressed religious belief.
