This genre became colloquially known as yellow music, in opposition to the nhạc đỏ (red music) endorsed by the Communist government of Hanoi during the era of the Vietnam War. As a result of North Vietnam winning the war, the music was banned in 1975. Those caught listening to yellow music would be punished, and their music confiscated.
