GBH are an English punk rock band which was formed in 1978 by vocalist Colin Abrahall, guitarist Colin "Jock" Blyth, bassist Sean McCarthy and drummer Andy "Wilf" Williams.

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.
