released its debut single, "Pay to Cum", in 1980, and were influential in establishing the D.C. hardcore scene. Hardcore historian Steven Blush calls the single the first East coast hardcore record. Ian MacKaye and Jeff Nelson, influenced by Bad Brains, formed the band Teen Idles in 1979. The group broke up in 1980, and MacKaye and Nelson went on to form Minor Threat, a band which, apart from Bad Brains, has arguably had the biggest influence on the hardcore punk genre, and whose contributions to the music, ethics, aesthetic, and ethos are still widely acknowledged by hardcore bands of the 2020s. The band used faster rhythms and more aggressive, less melodic riffs than was common at the time. Minor Threat popularized the straight edge movement with its song "Straight Edge", which spoke out against alcohol, drugs and promiscuity. MacKaye and Nelson ran their own record label, Dischord Records, which released records by D.C. hardcore bands including: the Faith, Iron Cross, Scream, State of Alert, Government Issue, Void, and DC's Youth Brigade. The Flex Your Head compilation was a seminal document of the early 1980s DC hardcore scene. The record label was run out of the Dischord House, a Washington, D.C. punk house. Henry Rollins, who would come to prominence as lead singer of the California-based Black Flag, as well as his own later Rollins Band, grew up in Washington D.C., singing for State of Alert, and was influenced by the music of Bad Brains and the bands of his childhood friend Ian MacKaye. The tradition of holding all ages shows at small D.I.Y. spaces, has roots in the early Washington, DC straight edge movement. It emerged from the idea that people of all ages should have access to music, regardless of if they're old enough to drink alcohol. Boston Seminal Boston area hardcore bands included the F.U.'s, the Freeze, Gang Green, Jerry's Kids, Siege, DYS, Negative FX, and SS Decontrol. Members of the latter three bands were influenced by D.C.'s straight edge scene, and were part of "the Boston Crew", a mostly straight edge group of friends known to physically fight people who used alcohol or drugs. Members of the Boston Crew would later go on to form the band Slapshot, and also included future Mighty Mighty Bosstones singer Dicky Barrett, who was then a member of the band Impact Unit, and drew the artwork for the DYS album Brotherhood.
