Nhạc đỏ
Nhạc đỏ or literally "red music", is the common name of the revolutionary music (nhạc cách mạng) genre in Vietnam. Red music was formed during the communist Việt Minh and the First Indochina War and later strongly promoted across communist North Vietnam during the Vietnam War, to urge Northerners to achieve reunification under the Workers' Party of Vietnam and fight against the "American imperialist puppet" in South Vietnam.
