Punk rock (or simply punk) is a subgenre of rock music that emerged in the mid-1970s. Rooted in 1950s rock and roll and 1960s garage rock, punk bands rejected the overproduction and corporate nature of mainstream rock music. Typically producing short, fast-paced songs with rough stripped-down vocals and instrumentation and an anti-establishment theme, artists embrace a DIY ethic with many bands self-producing and distributing recordings through independent labels.
