The first rock band of Mongolia was Soyol Erdene, founded in the 1960s. Their Beatles-like manner was severely criticized by the communist censorship. It was followed by Mungunhurhree, Ineemseglel, Urgoo, etc., carving out the path for the genre in the harsh environment of communist ideology. Mungunhurhree and Haranga were to become the pioneers in the Mongolia's heavy rock music. Haranga approached its zenith in the late 1980s and 1990s.
