Les Horribles Cernettes (French pronunciation: ​[le.z‿ɔʁiblə sɛʁnɛt], "The Horrible CERN Girls") was an all-female parody pop group, self-labelled "the one and only High Energy Rock Band", which was founded by employees of CERN and performed at CERN and other HEP-related events. Their musical style is often described as doo-wop. The initials of their name, LHC, are the same as those of the Large Hadron Collider, which was later built at CERN. Their humorous songs are freely available on their website.
