Question: What genre of music, rooted in 1960s garage rock, does Dischord Records specialize in?

full_context: Document 1: Epitaph Records: Epitaph Records is a Hollywood-based independent record label owned by Bad Religion guitarist Brett Gurewitz. The label was originally "just a logo and a P.O. box" created in the 1980s for the purpose of selling Bad Religion records, but has evolved into a large independent record label. Gurewitz took the name from a King Crimson song of the same name. Throughout the 1980s and 1990s most of the bands on Epitaph were punk and pop punk groups, while there are many post-hardcore and bands signed to the label as well. A large portion of the record label, known as Hellcat Records, is owned by Tim Armstrong, frontman of the punk rock band Rancid. Several sister-labels also exist, such as ANTI-, Burning Heart Records, Fat Possum Records, Hellcat Records and Heart & Skull Records that have signed other types of bands. The label has recently been added to the Forza Horizon franchise as a radio station.
Document 2: Jeff Nelson (musician): Jeff Nelson (born 1962 in South Africa) is an American drummer and graphic designer. He is best known as the drummer for the Washington, D.C. hardcore punk band Minor Threat. Nelson and friend Ian MacKaye formed their first band, The Slinkees, in 1979. Their next band was The Teen Idles. He also co-founded the independent record label Dischord Records along with MacKaye in 1980, whose first record was the Teen Idles. They continue to run Dischord together. The duo also comprised the projects Skewbald/Grand Union and Egg Hunt; both bands recorded only one single. Nelson has also played in the bands Feedbag, Three, Wonderama, Senator Flux, High Back Chairs, and Fast Piece of Furniture. He founded Pedestrian Press in 1988 and Adult Swim Records in 1989. An aficionado and collector of Jeep Wagoneers and Victorian architecture, Nelson currently lives in the historic "Old West End" of Toledo, Ohio. In 2008 he formed a community organization called Save Our Scott, which led the fight to save Toledo's oldest high school, built in 1912. (Jessup W. Scott High School was saved, and underwent a $42 million renovation).
Document 3: Hardcore punk: Hardcore punk (often abbreviated to hardcore) 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 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 with "confrontational, politically-charged lyrics".
Document 4: List of punk rock bands, 0–K: This is a list of notable punk rock bands (numbers 0–9 and letters A through K). The bands listed have played some type of punk music at some point in their career, although they may have also played other styles. Bands who played in a style that influenced early punk rock—such as garage rock and protopunk—but never played punk rock themselves, should not be on this list. Bands who created a new genre that was influenced by (but is not a subgenre of) punk rock—such as alternative rock, crossover thrash, metalcore, new wave, and post-punk—but never played punk rock, should not be listed either.
Document 5: Dischord Records discography: Dischord Records is a Washington, D.C.-based independent record label specializing in the independent punk music of the D.C.-area music scene. The company is co-owned by Ian MacKaye and Jeff Nelson, who founded the label in December 1980. Before founding Dischord, both MacKaye and Nelson were members of the Teen Idles, and the label was initially meant to only foster a single release from the defunct band, the "Minor Disturbance" EP. By the time Dischord #1 was finished, many new bands had emerged from the same music scene, and like the Teen Idles, also began releasing their records through Dischord.
Document 6: Punk rock: Punk rock (or "punk") is a rock music genre that developed in the early to mid-1970s in the United States, United Kingdom, and Australia. Rooted in 1960s garage rock and other forms of what is now known as "proto-punk" music, punk rock bands rejected perceived excesses of mainstream 1970s rock. Punk bands typically produced short or fast-paced songs, with hard-edged melodies and singing styles, stripped-down instrumentation, and often political, anti-establishment lyrics. Punk embraces a DIY ethic; many bands self-produce recordings and distribute them through informal channels.
Document 7: List of rock genres: This is a list of rock music genres consisting of subgenres of popular music that have roots in 1940s' and 1950s' rock and roll, and which developed into a distinct identity as rock music in the 1960s, particularly in the United Kingdom and the United States. By the late 1960s, a number of identifiable rock music subgenres had emerged, including hybrids like blues rock, folk rock, country rock, and jazz-rock fusion, many of which contributed to the development of psychedelic rock influenced by the counter-cultural psychedelic scene. New genres that emerged from this scene included progressive rock, which extended the artistic elements; glam rock, which highlighted showmanship and visual style; and the diverse and enduring major subgenre of heavy metal, which emphasized volume, power, and speed. In the second half of the 1970s, punk rock both intensified and reacted against some of these trends to produce a raw, energetic form of music characterized by overt political and social critiques. Punk was an influence into the 1980s on the subsequent development of other subgenres, including new wave, post-punk and eventually the alternative rock movement. From the 1990s alternative rock began to dominate rock music and break through into the mainstream in the form of grunge, Britpop, and indie rock. Further fusion subgenres have since emerged as well as conscious attempts to revisit rock's history.
Document 8: Garage punk (fusion genre): Garage punk is a rock music fusion genre combining punk rock and garage rock that took shape in the indie rock underground between the late 1980s and early 1990s. Bands drew heavily from stripped-down 1970s punk rock and Detroit proto-punk, and incorporated numerous other styles into their approach, such as power pop, 1960s girl groups and garage rock, hardcore punk, early blues and R&B, and surf rock.
Document 9: Skate punk: Skate punk (also known as skate rock, skatecore and skate-thrash) is a skater subculture and a subgenre of punk rock music. Originally a genre of hardcore punk, skate punk changed into a more melodic genre of punk rock in the 1990s. The term usually describes the sound of 1990s punk rock bands that have a fast, melodic sound, and similar 21st-century punk rock bands. Skate videos have traditionally featured this fast style of punk rock. This played a big part in the coining of the term "skate punk".
Document 10: Protest Records: Protest Records is a subversive, online record label that creates mp3 compilation albums, which are released for free download. The label was founded by Thurston Moore and Kim Gordon of Sonic Youth with Stephan Said. The original intent of the label was to actually produce vinyl LPs, which would have been secretly placed in records stores; the goal was to confuse record store clerks because the records would not have been in their computer system. This plan was rejected when the label owners realized it would be cost prohibitive. The label intended to release at least ten "volumes" or compilation albums but to date has released only eight. The label is now defunct in that it does not receive any new submissions and does not intend to release new material in the immediate future, but pledges to continues to host the previously released albums online. Some well-known artists who have been released on Protest Records include Beastie Boys (vol. 1), Cat Power (vol. 1), Sonic Youth (vol. 2), DJ Spooky (vol 3.), Saul Williams (vol 3.), Mudhoney (vol. 4), Chumbawamba (vol. 5), and Allen Ginsberg (vol. 7). The motto of the label is: "use 'em for yrself. give 'em to friends. just don't sell 'em".
Document 11: Pub rock (United Kingdom): Pub rock is a rock music genre that was developed in the early to mid-1970s in the United Kingdom. A back-to-basics movement which incorporated roots rock, pub rock was a reaction against expensively-recorded and produced progressive rock and flashy glam rock. Although short-lived, pub rock was notable for rejecting huge stadium venues and for returning live rock to the small intimate venues (pubs and clubs) of its early years. Since major labels showed no interest in pub rock groups, pub rockers sought out independent record labels such as Stiff Records. Indie labels used relatively inexpensive recording processes, so they had a much lower break-even point for a record than a major label.
Document 12: Ian MacKaye: Ian Thomas Garner MacKaye ( ; born April 16, 1962) is an American singer, songwriter, guitarist, musician, record label owner and producer. Active since 1979, MacKaye is best known as the co-founder and owner of Dischord Records, a Washington, D.C.-based independent record label and the frontman of the influential hardcore punk band Minor Threat and the post-hardcore band Fugazi. MacKaye was also the frontman for the short-lived bands The Teen Idles, Embrace and Pailhead, a collaboration with the band Ministry. MacKaye is a member of The Evens, a two-piece indie rock group he formed with his wife Amy Farina in 2001.
Document 13: Dischord Records: Dischord Records is a Washington, D.C.-based independent record label specializing in the independent punk rock music of the D.C.-area music scene. The label is co-owned by Ian MacKaye and Jeff Nelson, who founded Dischord in 1980 to release "Minor Disturbance" by The Teen Idles. Along with other independent American labels such as Twin/Tone, Touch and Go Records, and SST Records, Dischord helped to spearhead the nationwide network of underground bands that formed the 1980s indie-rock scene. These labels presided over the shift from the hardcore punk that then dominated the American underground scene to the more diverse styles of alternative rock that were emerging.
Document 14: List of punk rock bands, L–Z: This is a list of notable punk rock bands (letters L through Z). The bands listed have played some type of punk music at some point in their career, although they may have also played other styles. Bands who played in a style that influenced early punk rock—such as garage rock and protopunk—but never played punk rock themselves, should not be on this list. Bands who created a new genre that was influenced by (but is not a subgenre of) punk rock—such as alternative rock, crossover thrash, grunge, metalcore, new wave, and post-punk—but never played punk rock, should not be listed either.
Document 15: Rozzlyn Rangers: Rozzlyn Rangers was the name taken by the 5 original members of the Dischord House in Arlington, Virginia (fairly near Rosslyn, Virginia) in October 1981: Ian MacKaye, Jeff Nelson, Rich Moore, Eddie Janney, and Sab Grey. Dischord House housed Dischord Records (founded a year earlier by The Teen Idles, shortly thereafter to be run by Ian MacKaye and Jeff Nelson). Despite its terribly low ceiling, many DC punk bands practiced in its basement over the years: Minor Threat, Skewbald, Iron Cross, The Faith, Second Wind, Rites of Spring, Embrace, Three, Fugazi, Beefeater, Fidelity Jones, Happy Go Licky, Kingface, One Last Wish, The Evens.
