His own band Dio set a template for theatrical, fantasy-infused metal that bands like Iron Maiden and Helloween would later build upon.
The meaning of “Holy Diver” has been debated for decades. Dio explained that the song tells the story of a figure who dives into the sea to save souls, drawing on baptismal imagery.
