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, shouts 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.
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."
Screamo is an aggressive subgenre of emo that emerged in the early 1990s and emphasizes "willfully experimental dissonance and dynamics". San Diego-based bands Heroin and Antioch Arrow pioneered the genre in the early 1990s, and it was developed in the late 1990s mainly by bands from the East Coast of the United States such as Pg. 99, Orchid, Funeral Diner, Saetia, and I Hate Myself. 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 frequently been mistaken as referring to any music with screaming.
Crust punk is a form of music influenced by English punk rock and extreme metal. The style, which evolved in the early 1980s in England, often has songs with dark and pessimistic lyrics that linger on political and social ills. The term "crust" was coined by Hellbastard on their 1986 Ripper Crust demo.
Sludge metal is an extreme subgenre of heavy metal music that originated through combining elements of doom metal and hardcore punk. It is typically harsh and abrasive, often featuring shouted vocals, heavily distorted instruments and sharply contrasting tempos. The Melvins from the US state of Washington produced the first sludge metal albums in the mid-late 1980s.
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 the term "post-punk", the term "post-hardcore" 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, Jawbox, Quicksand, and Shellac that stuck closer to post-hardcore's noise rock roots. Dischord Records became a major nexus of post-hardcore during this period. The genre also began to incorporate more dense, complex, and atmospheric instrumentals with bands like Slint and Unwound, and also experienced some crossover from indie rock with bands like The Dismemberment Plan. In the early- and mid-2000s, post-hardcore achieved mainstream success with the popularity of bands like At the Drive-In, My Chemical Romance, Dance Gavin Dance, AFI, Underoath, Hawthorne Heights, Silverstein, The Used, Saosin, Alexisonfire, and Senses Fail. In the 2010s, bands like Sleeping with Sirens and Pierce the Veil achieved mainstream success under the post-hardcore label. Meanwhile, bands like Title Fight and La Dispute experienced underground popularity playing music that bore a closer resemblance to the post-hardcore bands of the 1980s and 1990s.
Discharge are an English hardcore punk band formed in 1977 in Stoke-on-Trent, England. The band is known for influencing several sub-genres of extreme music and their songs have been covered by some of the biggest names in heavy metal and other genres. The musical sub-genre of D-beat is named after Discharge and the band's distinctive drumbeat.
D-beat is a style of hardcore punk, developed in the early 1980s by imitators of Discharge, after whom the genre is named, as well as a drum beat characteristic of this subgenre. D-beat is known for its "grinding, distorted and brutally political" sound. Discharge may have themselves inherited the beat from Motörhead and the Buzzcocks. D-beat is closely associated with crust punk, which is a heavier, more complex variation. The style was particularly popular in Sweden, and developed there by groups such as Crude SS, Anti Cimex, Mob 47, and Driller Killer. Other D-beat groups include Doom and the Varukers from the UK; Disclose from Japan; Crucifix and Final Conflict from the U.S.; Ratos de Porão from Brazil; and MG15 from Spain. While the style initially developed in the early 1980s, a number of new groups working within the subgenre emerged in the mid-1990s. These include the Swedish groups Wolfbrigade, Totalitär, Avskum, Skitsystem, and Disfear.
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.
Converge is an American metallic hardcore band formed by vocalist and artist Jacob Bannon and guitarist and producer Kurt Ballou in Salem, Massachusetts in 1990.

This lineup has remained intact since. The members have also been involved in various side-projects and collaborations, including the bands Supermachiner (Bannon), Old Man Gloom (Newton), and Mutoid Man (Koller). With their extremely aggressive and boundary-pushing sound, rooted in hardcore and heavy metal, they are pioneers of metalcore and its subgenre mathcore.
