Korean rock (Korean: 한국의 록) is rock music from South Korea.[1] It has roots in American rock, which was imported to South Korea by U.S. soldiers fighting in the Korean War[2][3] and stationing in U.S. military bases in South Korea after the war. Around the U.S. military bases, local musicians could have opportunities to learn American rock music and perform it on stage for U.S. soldiers. As a result, many Korean rock bands, called Vocal Bands or Group Sound, started their musical careers in the 1960s. Under the military administration in the 1970s, rock music and its subculture were classified as a depraved youth culture and restricted. After the Korean Fifth Republic, the censorship policies under the military government were abolished and rock music became a mainstream genre in South Korea until the end of the 1980s. Today, rock music is not the main genre in the music market in South Korea, but it still occupies a big portion of music consumption in the nation.
