Rap music or hip-hop, genre originating in the mid-1970s among black and Hispanic performers in New York City, at first associated with an athletic style of dancing, known as breakdancing.

Detractors have criticized most rap music as a boastful promotion of violence and misogyny; others have admired it as an inventive manipulation of cultural idioms and credit many rappers with an acute social and political awareness. Early rap groups included Grandmaster Flash, Afrika Bambaataa, and the Beastie Boys. Rap has influenced many forms of popular culture, particularly film, and has been increasingly incorporated into pop music. Some influential rap performers include Public Enemy
