Punk rock (often referred to simply as punk) is an anti-establishment rock music genre and movement that developed between 1974 and 1976 in the United Kingdom, United States and Australia. Rooted in garage rock and other forms of what is now known as protopunk music, punk rock bands eschewed the perceived excesses of mainstream 1970s rock. They created fast, hard-edged music, typically with short songs, stripped-down instrumentation, and often political, anti-government lyrics. Punk embraces a DIY (do it yourself) ethic, with many bands self-producing their recordings and distributing them through informal channels. By late 1976, bands such as the Ramones, in New York City, and the Sex Pistols and The Clash, in London, were recognized as the vanguard of a new musical movement. The following year saw punk rock spreading around the world. Punk quickly, though briefly, became a major cultural phenomenon in the United Kingdom. For the most part, punk took root in local scenes that tended to reject association with the mainstream. An associated punk subculture emerged, expressing youthful rebellion and characterized by distinctive clothing styles and a variety of anti-authoritarian ideologies. By the beginning of the 1980s, even faster, more aggressive styles such as hardcore and Oi! had become the predominant mode of punk rock. Musicians identifying with or inspired by punk also pursued a broad range of other variations, giving rise to post-punk and the alternative rock movement. By the turn of the century, new pop punk bands such as Green Day were bringing the genre widespread popularity decades after its inception.
