People's Republic of Kampuchea Anthem (1979-1989; Instrumental)

The People's Republic of Kampuchea (PRK) was founded in Cambodia by the Salvation Front, a group of Cambodian communists dissatisfied with the Khmer Rouge, after the overthrow of Pol Pot's government.
The "Anthem of the People's Republic of Kampuchea" (Khmer: បទចម្រៀងនៃសាធារណរដ្ឋប្រជាមានិតកម្ពុជា) was the national anthem from 1979 to 1989.
