Post-Hardcore
Post-hardcore is a broad term which describes various musical styles and movements which emerged at the confluence of hardcore punk? intensity and art punk? eclecticism. The term has been abbreviated as PxH or PHxC, in line with the "HxC" moniker from straight edge? hardcore punk.
The "post-hardcore" term emerged in the early to mid-1980s?, referring not to any specific style but to a number of largely post-punk and early noise rock bands who took influence from hardcore in more arty and experimental directions, as well as hardcore-scene veterans like Black Flag?, Husker Du?, and the Meat Puppets?. Amerindie groups Sonic Youth?, Big Black?, and Dinosaur Jr? had been described as "post-hardcore" by US? and UK? press by 1985?. That same year included the "Revolution Summer?" movement in Washington, DC?, which included artists like Rites of Spring? and Embrace?; these groups were derisively described as "emo-core?", which became established as a distinctive branch of post-hardcore music in the late 1980s into the early 1990s?, as it evolved into emo?.
Beyond emocore, post-Rev Summer DC groups like Fugazi? and Soulside? pioneered more midtempo, groovy styles informed by post-punk and the grooves of funk? and reggae, eventually becoming the dominant "DC post-hardcore" sound associated with Dischord Records? through the 1990s.
