List of Dio members

Dio was formed in October 1982 by vocalist Ronnie James Dio and drummer Vinny Appice following their departure from Black Sabbath.[1] For the first lineup, the pair worked with Rough Cutt guitarist Jake E. Lee for around six weeks, before parting ways due to stylistic differences.[2] Preferring to work with British musicians, Dio approached former Wild Horses bassist Jimmy Bain for suggestions of a replacement; he recommended Sweet Savage guitarist Vivian Campbell, and the pair joined the group.[3] Around the release of the band's debut Holy Diver in May 1983, Claude Schnell joined as Dio's first full-time keyboardist.[4] After two more studio albums – The Last in Line and Sacred Heart – as well as live release Intermission, Campbell left the band in March 1986.[5] He was replaced by former Giuffria guitarist Craig Goldy.[6]

Goldy remained for just one new album, Dream Evil, before leaving Dio due to "musical differences" in August 1988.[7] After "hundreds" of submissions from guitarists worldwide, Rowan Robertson was chosen as Goldy's replacement in May 1989.[8] A few months later, Bain and Schnell were replaced by Teddy Cook and Jens Johansson, respectively.[9] In December, Appice also left Dio,[10] with Simon Wright leaving AC/DC to take his place early the next year.[11] The new lineup recorded and released their only album Lock Up the Wolves in 1990.[12] The following January, Dio returned to Black Sabbath.[13]

By November 1992, Dio and Appice had left Black Sabbath for a second time.[14] They reformed Dio and added new guitarist Tracy G and bassist Jeff Pilson early the following year, after initially working with original member Bain.[15] After recording Strange Highways, the group returned to a five-piece with the addition of Scott Warren on keyboards.[16] Pilson remained until the end of the album's tour in late 1994, when he rejoined Dokken, although he contributed to the 1996 release Angry Machines.[15] Larry "Bones" Dennison replaced him for the next tour, which spawned the live release Inferno: Last in Live.[17] In February 1997, Appice was replaced for a run of shows by James Kottak, after being hospitalised for pneumonia.[18] He was also next to leave Dio permanently, when he toured with Black Sabbath from June 1998.[19]

Appice was replaced, again, by Simon Wright.[20] The following year, former members Goldy and Bain also returned.[21][22] Again, Goldy only lasted one album – 2000's Magica – before he was replaced by Doug Aldrich in January 2002.[23] The new guitarist recorded Killing the Dragon, but by early 2003 had left due to "scheduling conflicts" with his other group Whitesnake.[24] Aldrich was originally set to be replaced by Ratt guitarist Warren DeMartini,[25] however he was replaced within a month by the returning Goldy.[26] Bain also left in early 2004.[27] Pilson returned to perform on Master of the Moon, with former Ozzy Osbourne bassist Rudy Sarzo taking over on tour from July.[28] Aldrich would later return to fill in for Goldy on tour in 2005 due to an arm injury,[29] and again in 2009 due to scheduling conflicts with Budgie.[30]

On May 16, 2010, Ronnie James Dio died of stomach cancer, marking the end of his eponymous band.[31] All four other members went on to form Dio Disciples with former Judas Priest frontman Tim "Ripper" Owens in 2011,[32] while original members Appice, Campbell, Bain and Schnell formed Last in Line with former Lynch Mob vocalist Andrew Freeman in 2012.[33]
