Dio

Dio was an American heavy metal band formed in 1982 and led by vocalist Ronnie James Dio. Dio left Black Sabbath with intentions to form a new band with fellow former Black Sabbath member, drummer Vinny Appice. The band released ten studio albums and had numerous lineup changes over the years, with Dio himself being the only constant member.

In 2016, Loudwire ranked Dio the 15th greatest metal band of all time, calling their song "Holy Diver" genre defining.

The band dissolved in 2010 when Ronnie James Dio died of stomach cancer at the age of 67. Ronnie James Dio has sold over 50 million records worldwide.
