2019 collection. 8-Tracks Classics Live includes some of Dio's biggest hits including 'Holy Diver', 'Heaven & Hell', and 'Push'. Dio was an American heavy metal band formed in 1982 and led by vocalist Ronnie James Dio, after he left Black Sabbath with intentions to form a new band with fellow former Black Sabbath member, drummer Vinny Appice. The name Dio was chosen because it made sense from a commercial standpoint, as the name was already well known at that time. The band released ten studio albums and had numerous line-up changes over the years with Ronnie James Dio having been the only constant member. The band has sold more than 10 million copies of albums worldwide.
