The term 'Love-Rock Musical' refers to a genre of musical theater that combines elements of rock music with themes of love and romance. The most famous example of this genre is the Broadway musical HAIR, which premiered in 1967 and was the first rock musical to be performed on Broadway. HAIR tells the story of a group of hippies living in New York City during the Vietnam War era and their struggles with issues such as racism, sexism, and the draft.
