Hardcore punk in the context of "Rites of Spring"

Screamo (also referred to as skramz) is a 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, 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.

Distortion and overdrive are forms of audio signal processing used to alter the sound of amplified electric musical instruments, usually by increasing their gain, producing a "fuzzy", "growling", or "gritty" tone. Distortion is most commonly used with the electric guitar, but may be used with other instruments, such as electric bass, electric piano, synthesizer, and Hammond organ. Guitarists playing electric blues originally obtained an overdriven sound by turning up their vacuum tube-powered guitar amplifiers to high volumes, which caused the signal to distort. Other ways to produce distortion have been developed since the 1960s, such as distortion effect pedals. The growling tone of a distorted electric guitar is a key part of many genres, including blues and many rock music genres, notably hard rock, punk rock, hardcore punk, acid rock, grunge and heavy metal music, while the use of distorted bass has been essential in a genre of hip hop music and alternative hip hop known as "SoundCloud rap".

The effects alter the instrument sound by clipping the signal (pushing it past its maximum, which shears off the peaks and troughs of the signal waves), adding sustain and harmonic and inharmonic overtones and leading to a compressed sound that is often described as "warm" and "dirty", depending on the type and intensity of distortion used. The terms distortion and overdrive are often used interchangeably; where a distinction is made, distortion is a more extreme version of the effect than overdrive. Fuzz is a particular form of extreme distortion originally created by guitarists using faulty equipment (such as a misaligned valve (tube); see below), which has been emulated since the 1960s by a number of "fuzzbox" effects pedals.

Emo (/ˈiːmoʊ/ EE-moh) is a genre of rock music that combines musical characteristics of hardcore punk with emotional, often confessional lyrics. It emerged as a style of hardcore punk and post-hardcore from the mid-1980s Washington, D.C., hardcore scene, where it was known as emotional hardcore or emocore. The bands Rites of Spring and Embrace, among others, pioneered the genre. In the early-to-mid 1990s, emo was adopted and reinvented by alternative rock, indie rock, punk rock, and pop-punk bands, including Sunny Day Real Estate, Jawbreaker, Cap'n Jazz, Mineral, and Jimmy Eat World. By the mid-1990s, Braid, the Promise Ring, American Football, and the Get Up Kids emerged from Midwest emo, and several independent record labels began to specialize in the genre. Meanwhile, screamo, a more aggressive style of emo using screamed vocals, also emerged, pioneered by the San Diego bands Heroin and Antioch Arrow. Screamo achieved mainstream success in the 2000s with bands like Hawthorne Heights, Silverstein, Story of the Year, Thursday, the Used, and Underoath.

The emo subculture signifies a specific relationship between fans and artists and certain aspects of fashion, culture, and behavior. Emo fashion includes skinny jeans, black eyeliner, tight t-shirts with band names, studded belts, and flat, straight, jet-black hair with long bangs. Since the early-to-mid 2000s, fans of emo music who dress like this are referred to as "emo kids" or "emos". The emo subculture was stereotypically associated with social alienation, sensitivity, misanthropy, introversion, and angst. Purported links to depression, self-harm, and suicide, combined with its rise in popularity in the early 2000s, inspired a backlash against emo, with some bands, including My Chemical Romance and Panic! at the Disco, rejecting the emo label because of the social stigma and controversy surrounding it. There has long been controversy over which bands are labeled "emo", especially for bands that started outside traditional emo scenes; a viral website, Is This Band Emo?, was created to address one fan's opinion on this question. Emo and its subgenre emo pop entered mainstream culture in the early 2000s with the success of Jimmy Eat World and Dashboard Confessional, and many artists signed contracts with major record labels. Bands such as My Chemical Romance, AFI, Fall Out Boy, and the Red Jumpsuit Apparatus continued the genre's popularity during the rest of the decade.

Heroin was an American hardcore punk band formed in San Diego, California, in 1989 within the underground Californian punk scene. They released 17 songs before breaking up in 1993, pioneering the screamo genre.

Pg. 99 (also spelled pageninetynine) is a hardcore punk band from Sterling, Virginia, a town on the outskirts of Washington, D.C., who are widely considered one of the pioneers of the screamo genre. The band formed as a six-piece in late 1997 and broke up as an eight-piece in 2003; at their maximum capacity they performed with two singers, three guitarists, two bassists and a drummer and were known for their intense live shows.

Screaming is an extended vocal technique that is usually harsh, loud and aggressive. While a few other genres have used screaming, it is especially popular in hardcore punk and extreme metal. Proper technique is required to scream safely, and some vocalists have experienced health issues due to improper screaming.

The Damned are an English rock band formed in London in 1976 by lead vocalist Dave Vanian, guitarist Brian James, bassist (and later guitarist) Captain Sensible and drummer Rat Scabies. They were the first punk band from the United Kingdom to release a single, "New Rose" (1976), release a studio album, Damned Damned Damned (1977) and tour the United States. Nine of the band's singles charted within the top 40 on the UK singles chart.

The band briefly dissolved after Music for Pleasure (1977), the follow-up to their debut studio album, was critically dismissed. They quickly re-formed without Brian James and released Machine Gun Etiquette (1979). In the 1980s, they released four studio albums: The Black Album (1980), Strawberries (1982), Phantasmagoria (1985) and Anything (1986), which saw the band moving toward a gothic rock style. The latter two albums did not feature Sensible, who had left the band in 1984. In 1988, James and Sensible rejoined to play a series of reunion gigs, one of which was released the next year as the live album Final Damnation (1989). Their fast-driven punk rock has been cited for influencing and shaping the emergence of hardcore punk in the late 1970s and early 1980s in the United Kingdom and the United States.

Straight edge (sometimes abbreviated as sXe or signified by XXX or simply X) is a subculture of hardcore punk whose adherents refrain from using alcohol, tobacco, and other recreational drugs in reaction to the punk subculture's perceived excesses. Some adherents refrain from engaging in promiscuous or casual sex, follow a vegetarian or vegan diet and do not consume caffeine or prescription drugs. The term "straight edge" was adopted from the 1981 song "Straight Edge" by the hardcore punk band Minor Threat.

The straight-edge subculture emerged amid the early-1980s hardcore punk scene. Since then, a wide variety of various beliefs and ideas have been associated with the movement, including vegetarianism and animal rights. While the commonly expressed aspects of the straight edge subculture have been abstinence from alcohol, nicotine, and illegal drugs, there have been considerable variations. Disagreements often arise as to the primary reasons for living straight edge. Straight edge politics vary, from explicitly revolutionary to conservative. Some activists have approached Straight Edge with skepticism, ridicule or even outright hostility in part due to what they perceived as the straight edge movement's self-righteous militancy.

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. Like the term "post-punk", the term "post-hardcore" has been applied to a broad constellation of groups. Initially taking inspiration from post-punk and noise rock, 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 which had established hardcore scenes, such as Fugazi from Washington, D.C. as well as groups such as Big Black, Jawbox, Quicksand, and Shellac who 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.
