Rock fans should thank Ronnie James Dio, a famous heavy metal singer, for popularizing the “devil horns” that have become the real symbol of rocking all over the world. This sign represents power and a reference to metal music. Frontman for Rainbow and Black Sabbath assured he had borrowed a now-famous gesture from his granny who used it to ward off evil.
