and the prejudiced pictures of it). Indeed, many anarchists were introduced to the ideas of Anarchism through that symbolism and the anti-authoritarian sentiment which many punk songs expressed. Anarcho-punk, on the other hand, is a current that has been more explicitly engaged with anarchist politics, particularly in the case of bands such as Crass, Poison Girls, (early) Chumbawamba, The Ex, Flux of Pink Indians, Rudimentary Peni, The Apostles, Riot/Clone, Conflict, Oi Polloi, Sin Dios, Propagandhi, Citizen Fish, Bus Station Loonies etc. Many other bands, especially at the local level of unsigned groups, have taken on what is known as a "punk" or "DIY" ethic: that is, Doing It Yourself, indeed a popular Anarcho-punk slogan reads "DIY not EMI", a reference to a conscious rejection of the major record company. Some groups who began as 'anarcho-punk' have attempted to move their ideas into a more mainstream musical arena, for instance, Chumbawamba, who continue to support and promote anarchist politics despite now playing more dance music and pop influenced styles. The Folk Punk genre also heavily explores anarchist ideas in an inherently DIY fashion. Pat the Bunny, Ramshackle Glory, The Taxpayers, Mischief Brew, and Days N Daze are examples of thematically anarchist folk punk bands. Techno music is also connected strongly to anarchists and eco-anarchists, as many of the events playing these types of music are self-organised and put on in contravention of national laws. Sometimes doors are pulled off empty warehouses and the insides transformed into illegal clubs with cheap (or free) entrance, types of music not heard elsewhere and quite often an abundance of different drugs. Other raves may be held outside, and are viewed negatively by the authorities. In the UK, the Criminal Justice Bill (1994) outlawed these events (raves) and brought together a coalition of socialists, ravers and direct actionists who opposed the introduction of this 'draconian' Act of Parliament by having a huge 'party&protest' in the Centre of London that descended into one of the largest riots of the 1990s in Britain. Digital hardcore, an electronic music genre, is also overtly anarchist; Atari Teenage Riot is the most widely recognized digital hardcore band. Both Digital Hardcore, Techno and related genres are not the sole preserve of anarchists; people of many musical, political or recreational persuasions are involved in these musical scenes. Heavy metal bands such as Sweden's Arch Enemy and Germany's Kreator have also embraced anarchistic themes
