Quote:The goth subculture is a contemporary subculture found in many countries. It began in England during the early 1980s in the gothic rock scene, an offshoot of the Post-punk genre. The goth subculture has survived much longer than others of the same era, and has continued to diversify. Its imagery and cultural proclivities indicate influences from the 19th century Gothic literature along with horror films and to a lesser extent the BDSM culture.
The goth subculture has associated tastes in music, aesthetics, and fashion. Gothic music encompasses a number of different styles including Gothic rock, Darkwave, Deathrock, Ethereal, Neo-Medieval and Neoclassical. Styles of dress within the subculture range from deathrock, punk and Victorian style attire, or combinations of the above, most often with dark attire, makeup and hair.
