Korean revolutionary opera
Korean revolutionary opera (Korean: 조선혁명가극) is a tradition of revolutionary opera in North Korea inspired by Chinese Revolutionary Opera which blossomed during the Cultural Revolution. It is characterized by a highly melodramatic style and reoccurring themes of patriotism and glorification of Juche, President Kim Il Sung, and the working people, as well as a focus on socialist realist themes.
