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 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 punk subculture includes a diverse and widely known array of ideologies, fashion, and other forms of expression, visual art, dance, literature and film. It is largely characterised by anti-establishment views, the promotion of individual freedom, DIY ethics, the culture is originated from punk rock.
Hardcore punk is a punk rock music genre and subculture 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. It was also inspired by Washington D.C. and New York punk rock and early proto-punk. 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 with "confrontational, politically-charged lyrics."
Overkill is an American thrash metal band, formed in 1980 in New Jersey. They have gone through many line-up changes, leaving bassist D. D. Verni and lead vocalist Bobby "Blitz" Ellsworth as the only constant members. In addition to Verni and Ellsworth, Overkill's current lineup includes Dave Linsk on lead guitar, Derek Tailer on rhythm guitar and Jason Bittner on drums. Along with Nuclear Assault and Anthrax, whose one-time lead guitarist Dan Spitz was also an early member of Overkill, the band is one of the most successful East Coast thrash metal bands, and they are often called "the Motörhead of thrash metal", based on their unique playing style, which was influenced by punk rock and the new wave of British heavy metal. The band has a notable mascot named "Chaly", a skeletal bat with a skull-like face, horns, bony wings and green eyes, who has appeared on most of their album covers.
Thrash metal 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 deals with criticisms of The Establishment and concern over the destruction of the environment, and at times shares a disdain for Christian dogma resembling that of their black metal counterparts. The language is typically direct and denunciatory, an approach borrowed from hardcore punk.
Sepultura is a Brazilian heavy metal band from Belo Horizonte. Formed in 1984 by brothers Max and Igor Cavalera, the band was a major force in the groove metal, thrash metal and death metal genres during the late 1980s and early 1990s, with their later experiments drawing influence from alternative metal, world music, nu metal, hardcore punk, and industrial metal. Sepultura has also been credited as one of the second wave of thrash metal acts from the late 1980s to early-to-mid-1990s.
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.
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.
Screamo is an aggressive subgenre of emo that emerged in the early 1990s, emphasizing "willfully experimental dissonance and dynamics". It was pioneered by San Diego bands Heroin and Antioch Arrow and developed in the late 1990s mainly by bands from the East Coast of the United States such as Orchid, Funeral Diner, Saetia, and Pg. 99. Screamo is strongly influenced by hardcore punk and characterized by the use of screamed vocals. Lyrical themes usually include emotional pain, death, romance, and human rights. The term "screamo" has been frequently mistaken as referring to any music with screaming vocals.
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".
Metalcore is a fusion music genre that combines elements of extreme metal and hardcore punk. As with other styles blending metal and hardcore, such as crust punk and grindcore, metalcore is noted for its use of breakdowns, slow, intense passages conducive to moshing. Other defining instrumental qualities include heavy riffs and stop-start rhythm guitar playing, occasional blast beats, and double bass drumming. Vocalists in the genre typically use thrash or scream vocals. Some later metalcore bands combine this with clean singing, often during the chorus. Death growls and gang vocals are common. 1990s metalcore bands were inspired by hardcore while later metalcore bands were inspired by melodic death metal bands like At the Gates and In Flames.
Thrashcore is a fast tempo subgenre of hardcore punk that emerged in the early 1980s. Thrashcore is essentially sped-up hardcore, often using blast beats. Songs can be very brief, and thrashcore is in many ways a less dissonant, less metallic forerunner of grindcore. The genre is sometimes associated with skateboarder subculture.
Post-hardcore is a punk rock music genre that maintains the aggression and intensity of hardcore punk but emphasizes a greater degree of creative expression. It was initially inspired by post-punk and noise rock. Like post-punk, the term has been applied to a broad constellation of groups. Post-hardcore began in the 1980s with bands like Hüsker Dü and Minutemen. The genre expanded in the 1980s and 1990s with releases by bands from cities that had established hardcore scenes, such as Fugazi from Washington, D.C. as well as groups such as Big Black and Jawbox that stuck closer to post-hardcore's noise rock roots. In the 2000s, post-hardcore achieved mainstream success with the popularity of bands like My Chemical Romance, Dance Gavin Dance, AFI, Underoath, Hawthorne Heights, Silverstein, The Used, At the Drive-In, Saosin, and Senses Fail. In the 2010s, bands like Sleeping with Sirens and Pierce the Veil, both of which being labeled as post-hardcore, achieved mainstream success. Meanwhile, bands like Title Fight and La Dispute experienced underground popularity.
Mathcore is a subgenre of hardcore punk and metalcore influenced by post-hardcore, extreme metal and math rock that developed during the 1990s. Bands in the genre emphasize complex and fluctuant rhythms through the use of irregular time signatures, polymeters, syncopations and tempo changes. Early mathcore lyrics were addressed from a realistic worldview and with a pessimistic, defiant, resentful or sarcastic point of view.
New York hardcore is both the hardcore punk music created in New York City and the subculture and lifestyle associated with that music. New York hardcore grew out of the hardcore scene established in Washington, D.C., by bands such as Bad Brains and Minor Threat. Initially a local phenomenon of the 1980s and 1990s, New York hardcore eventually grew to establish an international reputation with little to moderate mainstream popularity but with a dedicated and enthusiastic underground following, primarily in Europe and the United States. With a history spanning over more than four decades many of the early New York hardcore bands are still in activity to this day. Some of them have been continuously or almost continuously active since their formation as well as having reunion shows.
Washington, D.C. hardcore, commonly referred to as DC hardcore, sometimes referred to in writing as harDCore, is the hardcore punk scene of Washington, D.C. Emerging in late 1979, it is considered one of the first and most influential punk scenes in the United States.
Groove metal is a subgenre of heavy metal music that began in the early 1990s. The genre achieved success in the 1990s and continued having some more success in the 2000s. Inspired by thrash metal and traditional heavy metal, groove metal features raspy singing and screaming, down-tuned guitars, heavy guitar riffs, and syncopated rhythms. Unlike thrash metal, groove metal is usually slower and also uses elements of traditional heavy metal. Pantera are often considered the pioneers of groove metal, and groove metal expanded in the 1990s with bands like White Zombie, Machine Head, Skinlab, and Sepultura. The genre continued in the 2000s with bands like Lamb of God, DevilDriver, Five Finger Death Punch, and Hellyeah.
Crossover thrash is a fusion genre of thrash metal and hardcore punk. The genre lies on a continuum between heavy metal and hardcore punk. Other genres on the same continuum, such as metalcore and grindcore, may overlap with crossover thrash.
