Rock Against Communism (RAC) started out as series of white power rock music concerts in the United Kingdom in the late 1970s, and is also a name for the subsequent music genre. Despite its name, RAC song lyrics rarely focus on the specific topic of anti-communism. Instead, RAC lyrics typically feature nationalist, neo-Nazi, anti-Semitic, anti-Gay and racist themes. Musically, the RAC genre is mostly comprised of Oi!, punk rock, southern rock and rock and roll. .
