Heavy metal musicHeavy metal (or simply metal) is a genre of rock music that developed in the late 1960s and early 1970s, largely in the United Kingdom and United States. With roots in blues rock, psychedelic rock and acid rock, heavy metal bands developed a thick, monumental sound characterized by distorted guitars, extended guitar solos, emphatic beats and loudness. In 1968, three of the genre's most famous pioneers – Led Zeppelin, Black Sabbath and Deep Purple – were founded. Though they came to attract wide audiences, they were often derided by critics.
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.
Thrash metalThrash metal (or simply thrash) is an extreme subgenre of heavy metal music characterized by its overall aggression and often fast tempo. The songs usually use fast percussive beats and low-register guitar riffs, overlaid with shredding-style lead guitar work. The lyrical subject matter often includes criticism of The Establishment, opposition to armed conflicts, and at times shares a disdain for the Christian religion with that of black metal. The language is typically direct and denunciatory, an approach borrowed from hardcore punk.
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.
Rock musicRock is a broad genre of popular music that originated as "rock and roll" in the United States in the late 1940s and early 1950s, developing into a range of different styles from the mid-1960s, particularly in the U.S. and the United Kingdom. It has its roots in 1940s and 1950s rock and roll, a style that drew directly from the blues and rhythm and blues genres of African-American music and from country music. Rock also drew strongly from genres such as electric blues and folk, and incorporated influences from jazz, classical, and other musical styles.
Doom metalDoom metal is an extreme subgenre of heavy metal music that typically uses slower tempos, low-tuned guitars and a much "thicker" or "heavier" sound than other heavy metal genres. Both the music and the lyrics are intended 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.
Viking metalViking metal is a subgenre of heavy metal music characterized by a lyrical and thematic focus on Norse mythology, Norse paganism, and the Viking Age. Viking metal is quite diverse as a musical style, to the point where some consider it more a cross-genre term than a genre, but it is typically seen as black metal with influences from Nordic folk music. Common traits include a slow-paced and heavy riffing style, anthemic choruses, use of both sung and harsh vocals, a reliance on folk instrumentation, and often the use of keyboards for atmospheric effect.
Punk rockPunk rock (also known as simply punk) is a music genre that emerged in the mid-1970s. Rooted in 1960s garage rock, punk bands rejected the perceived excesses of mainstream 1970s rock music. They typically produced short, fast-paced songs with hard-edged melodies and singing styles, stripped-down instrumentation, and often shouted political, anti-establishment lyrics. Punk embraces a DIY ethic; many bands self-produce recordings and distribute them through independent record labels.
