Ronnie James Dio and Bruce Dickinson are two of the most powerful voices heavy metal has ever heard. Dio brought myth and fantasy to life with a voice that carried pure strength and passion. His work with Rainbow Black Sabbath and Dio created an entire universe of metal storytelling. Dickinson meanwhile gave Iron Maiden its soaring operatic sound. His screams about war battle and glory turned every song into an epic. Dio gave metal its mystical heart while Dickinson gave it its heroic wings. Bot

Ronnie James Dio unleashed operatic power precision and mythic storytelling that transformed metal vocals into something majestic and larger than life. His voice carried unmatched control and intensity. Brian Johnson blasted into AC DC with gravel edged force leading Back in Black to become one of the biggest albums ever.
