YESTERDAY

Hardcore punk is a subgenre of punk rock that originated in North America and the UK in the late 1970s. The new sound was generally thicker, heavier and faster than earlier punk rock.[1] The songs are usually short, fast, and loud, covering topics such as politics, personal freedom, violence, social alienation, straight edge, veganism, war, and the hardcore subculture itself.[2][3][4] Traditional hardcore punk vocals were more in line with traditional punk rock vocals, tending to be shouted as opposed to sung, albeit more aggressive than punk rock. However, over time, a far more guttural shout has become commonplace within hardcore punk, which bears resemblance to a death growl in its throat-driven delivery, but retains the shouting essence of it. It could be argued that the growling nature of modern hardcore has led to the music being less accessible and made the social/political message of the music harder to understand. Traditional hardcore shouts are also still popular within hardcore.
RAW HARDCORE

In America, the music genre that became known as hardcore punk originated in different areas in the early 1980s, with notable centers of activity in California, Washington, D.C., Chicago, New York City, Michigan, Vancouver, Toronto and Boston. The origin of the term hardcore punk is uncertain. The Vancouver-based band D.O.A. may have helped to popularize the term with the title of their 1981 album, Hardcore '81.[5][6][7] Since most bands had little access to any means of production, hardcore lauded a do-it-yourself (DIY) approach. In most cities the hardcore scene relied on inexpensively-made DIY recordings created on four-track recorders and sold at concerts or by mail. Concerts were promoted by photocopied zines, community radio shows, and affixing posters to walls and telephone poles. Hardcore punk fans adopted a dressed-down style of T-shirts, jeans, and crewcut-style haircuts. While 1977-era punk had used DIY clothing as well, such as torn pants held together with safety pins, the dressed-down style of the 1980s hardcore scene contrasted with the more campy, elaborate and provocative fashion styles of late 1970s punk rockers, which included make-up, elaborate hairdos and avant-garde clothing experiments. During the same period, there was a parallel development in the United Kingdom of a British form of hardcore punk, which later became known as UK 82.[8] British hardcore bands such as Discharge and Chaos UK took the existing late 1970s punk sound and added the incessant, heavy drumbeats and distorted guitar sound of New Wave of British Heavy Metal (NWOBHM) bands such as Motörhead. This led to the development of the thrash
