Anarcho-Punk

Punk rock that promotes anarchism. The term anarcho-punk is sometimes applied exclusively to bands that were part of the original anarcho-punk movement in the United Kingdom in the late 1970s and early 1980s. Some use the term more broadly to refer to any punk or rock music with anarchist lyrical content, including crust punk, d-beat, folk punk, hardcore punk, garage punk or ska punk. Generally speaking anarcho-punk bands are often less focused on particular musical delivery and more on a totalized aesthetic that encompasses the entire creative process, from album and concert art, to political message, to the lifestyles of the band members themselves. The message is sometimes considered to be much more important than the music. It is not uncommon for anarcho-punk songs to lack the usual rock structure of verses and a chorus.
