For those that don't know what punk is here's a brief history:
Punk, since the mid-1970s, has been a movement of shock, rebellion and discontent. As time has progressed, punk has become an overt socio-political movement for some who identify themselves as punks. Bands like Dead Kennedys, Bad Religion, Crass, Conflict, Subhumans and many others helped to contribute to this ideological climate. In their lyrics, these bands expressed serious discontent with the systems and institutions that organize and control the world. They also offered analysis and potential solutions to the world's problems. This spirit is active to this day in punk music and has matured and expanded in its range.
