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. Dio means "God" in Italian.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.The band dissolved in 2010 when Ronnie James Dio died of stomach cancer at the age of 67. The band has sold more than 10 million copies of albums worldwide.Origins and Holy Diver (1982–1983)In 1982, disagreements originating over the mixing of Black Sabbath's Live Evil resulted in the departure of Ronnie James Dio and Vinny Appice from the band. Wanting to continue together as a band, the two formed Dio in October 1982 in the United States with Vivian Campbell (guitar) and Jimmy Bain (bass). The following May, the band released their debut album, Holy Diver. It featured two hit singles, "Rainbow in the Dark" and "Holy Diver", which gained popularity from MTV. Ronnie James Dio and Jimmy Bain played keyboards in the studio, but recruited keyboardist Claude Schnell for live shows in 1983 prior to the Holy Diver tour. Schnell played to the side of the stage on the first two tours before coming out front in 1985. Dio had this to say of the band's origins:The Last in Line to Dream Evil (1984–1989)Now a quintet with Schnell on keyboards, the band released their second studio album, The Last in Line, on July 2, 1984. It was followed by their third album, Sacred Heart, which was released on August 15, 1985.In 1985 Ronnie James Dio, Campbell and Bain also wrote the song "Stars" for the Hear 'n Aid project, with many other heavy metal luminaries of the time contributing. Campbell became unhappy working with Dio, and the rift between them culminated in Campbell being fired from Dio's band. Campbell was subsequently invited to join Whitesnake in 1987. Several songs were recorded live during the Sacred Heart tour for the 1986 Intermission EP with Campbell still on guitar, however the EP also contained the studio track "Time To Burn", which served to introduce fans to Craig Goldy as the new guitarist.On July 21, 1987 their fourth album Dream Evil was released. After Dream Evil, Goldy, wanting to pursue solo projects, left the band. In June 1989 18 year-old Rowan Robertson was announced as Goldy's successor but further changes were to follow, with Schnell, Bain, and Appice leaving the band.Changes (1990–1999)Schnell, Bain, and Appice were replaced, respectively, with Teddy Cook, Jens Johansson, and former AC/DC drummer Simon Wright. The new band released the album Lock Up the Wolves in the spring of 1990. During the tour, Ronnie James Dio had a chance meeting with former Black Sabbath bandmate Geezer Butler which led to that band's short-lived reunion, producing one album, Dehumanizer. After this Ronnie James Dio reassembled Dio once again, retaining only Appice on the drums. By early 1993 guitarist Tracy G, keyboardist Scott Warren of Warrant and bassist Jeff Pilson had all joined. During this era, the band abandoned fantasy themed songs and focused on modern issues. As a result some fans regard the albums made during this period—1993's Strange Highways, 1996's Angry Machines and the live album Inferno: Last in Live—as the worst in Dio's catalogue, while others view them positively as a step away from the outdated sound of the 1980s. With disappointing record sales for Angry Machines management wanted the band to go back to their earlier style prompting the departure of Tracy G to be replaced by the returning Craig Goldy.Comeback (2000–2004)Craig Goldy's return facilitated the release of Dio's eighth studio album in 2000, Magica, which was regarded by many as the band's "comeback album" and reached No. 13 on the Billboard independent charts. It featured the return not only of Goldy but of Simon Wright and Jimmy Bain, although on the European tour Chuck Garric played bass. A concept album, Magica features a return to the band's older, more successful sound, while increased use of keyboards gives it a modern feel. During the following tour, however, tensions rose between Goldy on the one hand and Bain and Ronnie James Dio on the other, as Goldy was dealing with the obligations of a family. Goldy left the band in January 2002 and was replaced with Doug Aldrich, whom Bain had met while recording a tribute album for Metallica. Because of his late arrival, Aldrich did not contribute much to Dio's ninth work, Killing the Dragon, which was written primarily by Ronnie James Dio and Bain. Killing The Dragon was released in 2002 through Spitfire Records and was well received in the metal community, making the Billboard top 200. Aldrich would stay in the band until April of the following year, when he, like Campbell before him, joined Whitesnake, prompting Goldy's return. Soon afterwards, Bain left the band.Master of the Moon and Split (2004–2010)Dio released their tenth studio album, Master of the Moon on August 30, 2004 in Europe through SPV Records and on September 7, 2004 in the United States through Sanctuary Records. The album features multi-instrumentalist Jeff Pilson (formerly of Dokken) on bass duties; however, because of prior obligations with Foreigner, he was only available for the recording sessions, and so was replaced by Rudy Sarzo on the tour.2005 saw the release of the Dio live album Evil or Divine – Live in New York City, which featured the same show that was released on DVD in 2003. Dio toured South America, Japan, Europe, and Russia in 2005. Their autumn tour was titled "An Evening With Dio" and featured a regular set, and then a second set of the band playing Holy Diver in its entirety. A DVD of the tour was filmed in London. The audio of this performance, a double CD named Holy Diver – Live was released in April 2006.In 2007, it was announced that Black Sabbath would reunite with Ronnie James Dio and go under the name Heaven & Hell. The band released The Devil You Know in 2009.Ronnie James Dio's involvement with Heaven & Hell delayed the recording of what was to be the follow-up to Master of the Moon, Magica II. The three-year hiatus was briefly interrupted for a 10 concert European mini-tour in May/June 2008, and was scheduled to be interrupted again in November/December 2009 with 22 concerts starting in the UK and ending in Germany. Doug Aldrich was to have filled in for Craig Goldy on guitar on these dates, who had other obligations. Dio intended to release a new single, entitled "Electra", to coincide with the tour. This would have been their first studio material in 5 years. The band also intended to record an album or two in 2010.On November 18, 2009 the European tour was cancelled due to Ronnie James Dio's hospitalization. He had been diagnosed with stomach cancer, and was undergoing treatment. His manager and wife Wendy Dio thanked well-wishers and said "After he kills this dragon, Ronnie will be back on stage, where he belongs, doing what he loves best, performing for his fans."On February 19, 2010, it was announced on Dio's official website that he would release a box set, entitled the Tournado Box Set, for limited purchase. The set includes the Killing the Dragon CD, Evil or Divine DVD (PAL format only), DVD bonus material, interviews, photo gallery, never-before-seen behind the scenes footage, promo video for the Killing the Dragon track "Push", exclusive Dio cards, and the bonus CD single "Electra" (which is the last song the band recorded), from the unfinished albums Magica II & Magica III.Death of Ronnie James DioRonnie James Dio died on May 16, 2010, of stomach cancer at the Texas Medical Center in Houston, Texas.On November 9, 2010, a posthumous live album was released. Titled 'Dio at Donington UK: Live 1983 & 1987', it features Dio's 1983 and 1987 appearances at the Monsters of Rock festival and showcases several songs from the Ronnie James Dio era of both Rainbow and Black Sabbath, in addition to songs from Dio's own catalogue.When being interviewed Classic Rock Magazine from the UK, Dio guitarist Craig Goldy stated "We were working on tracks for a new Dio album just before Ronnie died in May. And we did almost finish one song. Wendy [Dio, Ronnie's widow/manager\] has been talking about reissuing [DIO's\] 'Magica' album (originally released in 2000) with bonus tracks, including this one." Goldy goes on to say of the lyrics, that they were written by Dio when he was fighting cancer, and are "very emotional" and "hard to listen to without a lump at the back of your throat".On March 18, It was announced that the surviving members of the final line-up of Dio would embark on a project with former Judas Priest front man Tim "Ripper" Owens under the moniker DIO Disciples. The project has been touring extensively since 2011.In May 2012, former Dio guitarist Vivian Campbell, despite his long established feud with Dio, announced his intent to reunite the original Dio band for a potential series of shows.
