Crass, the band whose name and image is synonymous with the genres of "anarcho-punk" and "peace-punk," emerged in the second wave of punk rock which began immediately following the Sex Pistols in 1976. As a band, label, and collective Crass delivered on many of the ideas which were posited but never fully explored by the original punks: they made punk an explicitly ideological, revolutionary enterprise and they applied that ideology to every aspect of their art. They popularized the seminal anarcho-punk movement of the punk subculture and advocated direct action, animal rights and environmentalism.
