Rock_Against_Communism 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 and racist themes. Musically, the RAC genre is similar to styles such as Oi!, punk rock, southern rock, rock and roll and, to a lesser extent, heavy metal.
