Street punk is an urban working class-based subgenre of punk rock, which partly emerged as a rebellion against the perceived artistic pretensions of the first wave of British punk. Street punk emerged from the style of Oi! and hardcore punk bands. A key band in defining the aesthetic was the Exploited. Street punks generally have a much more ostentatious and flamboyant appearance than the working class or skinhead image cultivated by many Oi! groups. Street punks commonly sported multi-coloured hair, mohawks, tattoos, heavily studded vests and leather jackets, and clothing, especially plaids, adorned with political slogans, patches, and/or the names of punk bands. In the 1990s and 2000s, a street punk revival began with emerging street punk bands such as the Casualties.

Punk rock is a music genre that emerged in the mid-1970s. Rooted in 1950s rock and roll and 1960s garage rock, punk bands rejected the corporate nature of mainstream 1970s rock music. They typically produced short, fast-paced songs with hard-edged melodies and singing styles with stripped-down instrumentation. Lyricism in punk typically revolves around anti-establishment and anti-authoritarian themes. Punk embraces a DIY ethic; many bands self-produce recordings and distribute them through independent labels.
