In the 1970s, however, there was a decline in the country's rock scene as a result of the military dictatorship imposed by the 1973 coup d'état. From 1973 to 1990, all forms of rock music were prohibited (along with an important part of the cultural life), causing stagnation in the music industry. Nevertheless, an underground scene grew up with new genres such as heavy metal, punk and new wave music. Los Prisioneros were the most outstanding band of this era.
