Definitions

Extreme metal acts set themselves apart from traditional heavy metal acts, such as Iron Maiden, Judas Priest and Motörhead, by incorporating more abrasive musical characteristics such as higher tempos, increased aggression and a harsher extremity. In the majority of the world, extreme metal does not receive much radio-play or achieve high chart positions. Extreme metal's sonic excess is characterized by high levels of distortion (also in the vocals – growling, gargling or screaming), less focus on guitar solos and melody, emphasis on technical control, and fast tempos (at times, more than 200 beats per minute). Its thematic transgression can be found in more overt and/or serious references to Satanism and the darker aspects of human existence that are considered out of bounds or distasteful, such as death, suicide and war.Julian Schaap and Pauwke Berkers. "Grunting Alone? Online Gender Inequality in Extreme Metal Music" in ''IASPM Journal''. Vol.4, no.1 (2014) p. 103 "Visual transgression an includenbsp;... medieval weaponry ndbloody/horrific artwork." According to ethnographer Keith Kahn-Harris,Kahn-Harris, Keith, ''Extreme Metal: Music and Culture on the Edge'', Oxford: Berg, 2007, . the defining characteristics of extreme metal can all be regarded as clearly transgressive: the "extreme" traits noted above are all intended to violate or transgress given cultural, artistic, social or aesthetic boundaries. Kahn-Harris states that extreme metal can be "close to being ... formless noise", at least to the uninitiated listener. He states that with extreme metal lyrics, they often "offer no possibility of hope or redemption" and lyrics often reference apocalyptic themes. Extreme metal lyrics often describe Christianity as weak or submissive, and many songs express misanthropic views such as "kill every thing". A small number of extreme metal bands and song lyrics take radical (left or right) political stances; for example, the Swedish black metal band Marduk has commonly referenced the Nazi Panzer tanks, which can be seen in works such as '' Panzer Division Marduk'' (1999).

bands like Discharge, the Exploited and Amebix. The first thrash metal bands were inspired by the likes of Venom, Motörhead, the new wave of British heavy metal and hardcore punk. In 1983, Metallica released their debut album '' Kill 'Em All'', which is seen as the first thrash metal record, and would eventually be certified triple platinum. A few months later, Slayer released their own thrash metal album '' Show No Mercy''. These were "landmark releases characterized by speed, aggression, and an austere seriousness". Swedish band Bathory have been described as "the biggest inspiration for the Norwegian black metal movement of the early nineties". Their songs first appeared on the compilation ''Scandinavian Metal Attack'' in March 1984. Bathory's first and second albums respectively influenced

and death metal. Frontman Quorthon pioneered the shrieked vocals that later came to define black metal. Swiss band Hellhammer made "truly raw and brutal music" which likewise influenced both black and death metal. They released three demos, and an EP in April 1984. Hellhammer then transformed into Celtic Frost and released their first album '' Morbid Tales'' that October. Celtic Frost were a major influence on all styles of extreme metal. The German thrash metal bands Sodom, Kreator and Destruction "pushed the boundaries of extreme metal". Their first records '' In the Sign of Evil'' (1985), '' Endless Pain'' (1985) and '' Sentence of Death'' (1984) led the way for black metal and death metal bands. In the United States, death metal was pioneered by the bands Possessed and

. Possessed released the demo ''Death Metal'' in 1984 and their first record '' Seven Churches'' in November 1985. They have been described by music journalists and musicians as being "monumental" in developing the death metal style, or as being the first death metal band. Death also released a demo ''Death by Metal'' (under the name Mantas) in 1984. The band made a major impact in the emerging Florida death metal scene, and frontman Chuck Schuldiner has been credited as the "Father of Death Metal". Their debut album, '' Scream Bloody Gore'' (1987), has been described as "the first true death metal record". The front cover of the Sarcófago's 1987 debut album, '' I.N.R.I.'', was a major influence on black metal's corpse paint style make-up. That record is also considered one of the first-wave black metal albums that helped shape the genre. Their second album, '' The Laws of Scourge'', was one of the first technical death metal records to be released.
