Dio was an American heavy metal band from Portsmouth, New Hampshire. 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. Naming the band Dio made sense from a commercial standpoint, as the name was already well-known at that time. Dio in Italian means "God".
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. Guitarists have included Craig Goldy (most recent guitarist), Doug Aldrich, Vivian Campbell, Tracy G, Jake E. Lee and Rowan Robertson.
