Hip-hop and social injustice
Hip-hop music, developed in the South Bronx in the early 1970s, has long been tied to social injustice in the United States, particularly that of the African American experience. Hip-hop artists have spoken out in their lyrics against perceived social injustices such as police brutality, poverty, mass incarceration, and the war on drugs.
