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 States, the United Kingdom, 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.   Wikipedia
