Hardcore punk

Hardcore punk (commonly abbreviated to hardcore or hXc) is a punk rock subgenre and subculture that originated in the late 1970s. It is generally faster, harder, and more aggressive than other forms of punk rock music. 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 Washington, D.C., and New York punk rock and early proto-punk. Hardcore punk generally eschews 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".

Hardcore sprouted underground scenes across the United States in the early 1980s, particularly in Los Angeles, San Francisco, Washington, D.C., Boston, and New York, as well as in Canada and the United Kingdom. Hardcore has spawned the straight edge movement and its associated sub-movements, hardline and youth crew. Hardcore was heavily involved in the rise of the independent record labels in the 1980s and with the DIY ethics in underground music scenes. It has also influenced various music genres that have experienced widespread commercial success, including grunge and thrash metal.

Although the music genre started in English-speaking Western countries, notable hardcore scenes have existed in Italy, Japan and Brazil.
