Though most obviously a genre of rock music, the hardcore punk movement was also all about an overall aesthetic incorporating specific fashions in clothing and certain modes of behaviour.
Hardcore punk is described by many music critics to have originated in the late 1970s (1977 to be precise) in California. This was the time in which the band Black Flag first performed in the region. Characterised by loud, fast, and grungey sounds, this performance was also crucial in terms of disseminating the anarchic message associated with so many hardcore punk bands in the history of the genre. This was the era, too, in which the movement known as hardcore punk was strongly associated with independent bands and record labels, something which was highly consonant with the independent, anarchic views of band members.
Though several strands of the hardcore punk movement have remained strongly independent, it is safe to say that the movement has also got steadily more mainstream. Bands such as New York and Gallows are signed with mainstream record labels, for example. Moreover, other elements of the hardcore punk aesthetic, such as the mohican hairstyle, and prevalence of studs on clothing and accessories, have been adopted by mainstream culture, with many teenagers embracing these styles. As such, punk has in many ways grown from being a truly shocking and subversive marginal genre to a genre which people who do not hold strongly anti-authoritarian views have incorporated into their lives in some way so as to stand out from the crowd. The movement has also influenced many other bands and genres of music, such as thrashcore, grindcore, and many forms of electronic music. Indeed, hardcore punk is often found to be lurking at the roots of many unexpected present day albums!
