Crass were an English anarchist punk rock ban, formed in 1977 which promoted anarchism as a political ideology, way of living, and as a resistance movement. Crass popularized the seminal anarcho-punk movement and advocated direct action, animal rights, and environmentalism. The band used the "Do It Yourself" approach to produce sound collages, graphics, albums and films. Crass also criticized and attempted to subvert the dominant culture with messages promoting feminism, anti-racism, anti-war, and anti-globalization.
