Dio

Prior to forming the heavy metal band Dio in 1982, singer-songwriter Ronnie James Dio had fronted three major bands: Elf, Rainbow, and Black Sabbath.

∙ Dio’s Platinum debut, 1983’s Holy Diver, is a genre-defining heavy metal album that spawned two classic hits, “Holy Diver” and “Rainbow In the Dark.” ∙ Their lineup has included Def Leppard guitarist Vivian Campbell, Quiet Riot bassist Rudy Sarzo, and AC/DC drummer Simon Wright.

∙ Ronnie and bandmates Jimmy Bain and Vivian Campbell cowrote “Stars,” a single recorded by the all-star heavy metal project Hear ’n Aid to raise money for African famine relief.
