Crass were an English punk rock band that was formed in 1977, which promoted anarchism as a political ideology, way of living, and as a resistance movement. Crass popularised the seminal anarcho-punk movement of the punk subculture, and advocated direct action, animal rights, and environmentalism. The band both utilised and advocated a DIY punk ethic approach, producing sound collages, graphics, albums, and films. Crass also criticised mainstream culture and attempted to subvert it with messages promoting feminism, anti-racism, anti-war, and anti-globalisation.
