Formed after Ronnie James Dio's departure from Black Sabbath, Dio's first self-titled outfit featured the considerable talents of fellow Sabbath absconder Vinny Appice on drums, alongside ex-Rainbow bassist Jimmy Bain and guitarist Vivian Campbell.
The first result of this union was the explosive debut, Holy Diver, an album so strong that it would overshadow all the releases that followed. The Last In Line and Sacred Heart weren't exactly massive leaps away from this winning formula though the former was a notably more streamlined effort which leant more towards the then-burgeoning speed metal movement.
Sacred Heart featured a greater use of keyboards and more ambitious songwriting.
Sadly, due to disagreements between guitarist and singer, Sacred Heart was also the last recording to feature Vivian Campbell, who later became a fixture in Def Leppard.
Ronnie Dio was born Ronald Padavona. He passed away in 2010. Bassist Jimmy Bain died on 24 January 2016.
