Please answer the following question: Information:  - Doom metal is an extreme style of heavy metal music that typically uses slower tempos, low-tuned guitars and a much "thicker" or "heavier" sound than other metal genres. Both the music and the lyrics intend to evoke a sense of despair, dread, and impending doom. The genre is strongly influenced by the early work of Black Sabbath, who formed a prototype for doom metal with songs such as "Black Sabbath", "Children of the Grave", "Electric Funeral" and "Into the Void". During the first half of the 1980s, a number of bands from England (Pagan Altar, Witchfinder General), the United States (Pentagram, Saint Vitus, Trouble) and Sweden (Candlemass, Count Raven) defined doom metal as a distinct genre.  - Speed metal is an extreme subgenre of heavy metal music that originated in the late 1970s from new wave of British heavy metal (NWOBHM) roots. It is described by AllMusic as "extremely fast, abrasive, and technically demanding" music.  - Death 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 and screams, aggressive, powerful drumming featuring double kick or 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 invoke slasher film-stylized violence, religion (sometimes Satanism), occultism, Lovecraftian horror, nature, mysticism, mythology, philosophy, science fiction, and politics, and they may describe extreme acts, including mutilation, dissection, torture, rape, cannibalism, and necrophilia.  - Nuclear Assault is an American thrash metal band from New York City, formed after bassist Dan Lilker left Anthrax in 1984. After releasing five full-length albums and touring relentlessly throughout the 1980s and early 1990s, Nuclear Assault split up in 1995. They briefly reunited in 1997 and again in 2002, and are still active today.  - Dimmu Borgir (or or ) is a Norwegian symphonic black metal band from Oslo, Norway, formed in 1993. The name is derived from Dimmuborgir, a volcanic formation in Iceland, the name of which means "dark cities" or "dark castles/fortresses" in Icelandic, Faroese and Old Norse. The band has been through numerous lineup changes over the years; guitarist Silenoz and vocalist Shagrath are the only original members who still remain with guitarist Galder being a longstanding member.  - Black metal is an extreme subgenre and subculture 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.  - Hardcore punk (often abbreviated to hardcore) is a punk rock music genre that originated in the late 1970s. It is generally faster, harder, and more aggressive than other forms of punk rock. Its roots can be traced to earlier punk scenes in San Francisco and Southern California which arose as a reaction against the still predominant hippie cultural climate of the time and was also inspired by New York punk rock and early proto-punk. New York punk had a harder-edged sound than its San Francisco counterpart, featuring anti-art expressions of masculine anger, energy and subversive humor. Hardcore punk generally disavows commercialism, the established music industry and "anything similar to the characteristics of mainstream rock" and often addresses social and political topics.  - Extreme 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 or sound associated with the speed metal, thrash metal, death metal, black metal and doom metal genres. With the exception of doom metal, all of these genres are characterized by fast tempos, attesting to their roots in hardcore punk, which has also fused with extreme metal in the forms of crossover thrash, crust punk, grindcore, sludge metal and metalcore. Though many extreme sub-styles are not very well known to mainstream music fans, extreme metal has influenced an array of musical performers inside and outside of heavy metal.  - Thrash metal is an extreme subgenre of heavy metal music characterized by its fast tempo and overall aggression. The songs usually use fast percussive beats and low-register guitar riffs, overlaid with shredding-style lead work. The lyrics often deal with social issues and reproach for The Establishment, using direct and denunciatory language, an approach borrowed from hardcore punk.  - Grindcore is an extreme genre of music that originated in the early to mid-1980s. It draws inspiration from some of the most abrasive-sounding genres  including hardcore punk, thrash metal, crust punk, industrial, death metal and noise rock. Grindcore is characterized by a noise-filled sound that uses heavily distorted, down-tuned guitars, grinding overdriven bass, high speed tempo, blast beats, and vocals which consist of growls 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.  - The Netherlands  is the main constituent country of the Kingdom of the Netherlands. It is a densely populated country located in Western Europe with three island territories in the Caribbean.
