Problem: Background: Black Sabbath were an English rock band, formed in Birmingham in 1968, by guitarist and main songwriter Tony Iommi, bassist and main lyricist Geezer Butler, singer Ozzy Osbourne, and drummer Bill Ward. Black Sabbath are often cited as pioneers of heavy metal music. The band helped define the genre with releases such as Black Sabbath (1970), Paranoid (1970) and Master of Reality (1971). The band had multiple line-up changes, with Iommi being the only constant member throughout its history.
Context: While Ozzy Osbourne was working on new solo album material in 2006, Rhino Records released Black Sabbath: The Dio Years, a compilation of songs culled from the four Black Sabbath releases featuring Ronnie James Dio. For the release, Iommi, Butler, Dio and Appice reunited to write and record three new songs as Black Sabbath. The Dio Years was released on 3 April 2007, reaching number 54 on the Billboard 200, while the single "The Devil Cried" reached number 37 on the Mainstream Rock Tracks chart. Pleased with the results, Iommi and Dio decided to reunite the 1981 Mob Rules era line-up for a world tour. While the line-up of Osbourne, Butler, Iommi and Ward were still officially called Black Sabbath, the new line-up opted to call themselves Heaven & Hell, after the album of the same name, to avoid confusion. When asked about the name of the group, Iommi stated "it really is Black Sabbath, whatever we do... so everyone knows what they're getting [and] so people won't expect to hear 'Iron Man' and all those songs. We've done them for so many years, it's nice to do just all the stuff we did with Ronnie again." Ward was initially set to participate, but dropped out before the tour began due to musical differences with "a couple of the band members". He was replaced by former drummer Vinny Appice, effectively reuniting the line-up that had featured on the Mob Rules (1981) and Dehumanizer (1992) albums. Heaven & Hell toured the U.S. with openers Megadeth and Machine Head, and recorded a live album and DVD in New York on 30 March 2007, titled Live from Radio City Music Hall. In November 2007, Dio confirmed that the band had plans to record a new studio album, which was recorded in the following year. In April 2008 the band announced the upcoming release of a new box set and their participation in the Metal Masters Tour, alongside Judas Priest, Motorhead and Testament. The box set, The Rules of Hell, featuring remastered versions of all the Dio fronted Black Sabbath albums, was supported by the Metal Masters Tour. In 2009, the band announced the name of their debut studio album, The Devil You Know, released on 28 April. On 26 May 2009 Osbourne filed suit in a federal court in New York against Iommi alleging that he illegally claimed the band name. Iommi noted that he has been the only constant band member for its full 41-year career, and that his bandmates relinquished their rights to the name in the 1980s, therefore claiming more rights to the name of the band. Although, in the suit, Osbourne was seeking 50% ownership of the trademark, he said that he hoped the proceedings would lead to equal ownership among the four original members. In March 2010, Black Sabbath announced that along with Metallica they would be releasing a limited edition single together to celebrate Record Store Day. It was released on 17 April 2010. Ronnie James Dio died on 16 May 2010 from stomach cancer. In June 2010, the legal battle between Ozzy Osbourne and Tony Iommi over the trademarking of the Black Sabbath name ended, but the terms of the settlement have not been disclosed.
Question: How long was Ronnie James Dio with the band?
Answer:

Background: Journey is an American rock band that formed in San Francisco in 1973, composed of former members of Santana and Frumious Bandersnatch. The band has gone through several phases; its strongest commercial success occurred between 1978 and 1987. During that period, the band released a series of hit songs, including "Don't Stop Believin'" (1981), which in 2009 became the top-selling track in iTunes history among songs not released in the 21st century. Its parent studio album, Escape, the band's eighth and most successful, reached No. 1 on the Billboard 200 and yielded another of their most popular singles, "Open Arms".
Context: Journey's album sales did not improve and Columbia Records requested that they change their musical style and add a frontman, with whom keyboardist Gregg Rolie could share lead vocal duties. The band hired Robert Fleischman and transitioned to a more popular style, akin to that of Foreigner and Boston. Journey went on tour with Fleischman in 1977 and together the new incarnation of the band wrote the hit "Wheel in the Sky"; however, management differences resulted in Fleischman leaving within the year. In late 1977, Journey hired Steve Perry as their new lead singer. Herbie Herbert, the band's manager, also hired Roy Thomas Baker as a producer to add a layered sound approach as Baker had done with his previous band, Queen. With their new lead singer and talented new producer, Journey released their fourth album, Infinity (1978). This album set Journey on their road to stardom with their first RIAA-certified platinum album. This album, with their hit song "Wheel in the Sky" (#57 U.S.), set Journey on a new path with a more mainstream sound to make their highest chart success to date. In late 1978, manager Herbie Herbert fired drummer Aynsley Dunbar, who joined Bay Area rivals Jefferson Starship shortly thereafter. He was replaced by Berklee-trained jazz drummer Steve Smith. Perry, Schon, Rolie, Smith and Valory recorded Evolution (1979), which gave the band their first Billboard Hot 100 Top 20 single, "Lovin', Touchin', Squeezin'" (#16); and Departure (1980), which reached No. 8 on the album charts. Journey's newfound success brought the band an almost entirely new fan base. During the 1980 Departure world tour, the band recorded a live album, Captured. Keyboardist Gregg Rolie then left the band, the second time in his career he left a successful act. Keyboardist Stevie "Keys" Roseman was brought in to record the lone studio track for Captured, "The Party's Over (Hopelessly in Love)," but Rolie recommended pianist Jonathan Cain of The Babys as the permanent replacement. With Cain's replacement of Rolie's Hammond B-3 organ with his own synthesizers, the band was poised for a new decade in which they would achieve their greatest musical success.
