===1979–1982: Dio joins, ''Heaven and Hell'' and ''Mob Rules''===
[[File:Dio IronFest.jpg|thumb|Ronnie James Dio's first stint as the singer of Black Sabbath lasted from 1979 to 1982.]]
While Don Arden was trying to convince Osbourne to rejoin Black Sabbath, as he viewed the original line-up as the most profitable,{{sfn|Iommi|2012}} the band hired former [[Rainbow (rock band)|Rainbow]] frontman [[Ronnie James Dio]] as Osbourne's replacement, and they began writing their next album. With a notably different vocal style from Osbourne's, Dio's addition to the band marked a change in Black Sabbath's sound. "They were totally different altogether", Iommi explains. "Not only voice-wise, but attitude-wise. Ozzy was a great showman, but when Dio came in, it was a different attitude, a different voice and a different musical approach, as far as vocals. Dio would sing ''across'' the riff, whereas Ozzy would follow the riff, like in "Iron Man". Ronnie came in and gave us another angle on writing."{{sfn|Rosen|1996|p=98}}

Butler temporarily left the band in September 1979 to deal with the divorce from his first wife. According to Dio, the band initially hired [[Craig Gruber]], with whom Dio had previously played while in [[Elf (band)|Elf]] and [[Rainbow (rock band)|Rainbow]], on bass to assist with writing the new album.<ref>{{Cite web|url=https://hardrockdaddy.com/2017/04/25/day-hard-rock-black-sabbath-releases-heaven-hell/|title=This Day in Hard Rock: Black Sabbath Releases 'Heaven And Hell'|date=25 April 2017|website=Hard Rock Daddy|language=en-US|access-date=22 January 2019}}</ref> Gruber was soon replaced by [[Geoff Nicholls]] of [[Quartz (metal band)|Quartz]]. The new line-up returned to [[Criteria Studios]] in November to begin recording work, with Butler returning to the band in January 1980 and Nicholls moving to keyboards. Produced by [[Martin Birch]], ''[[Heaven and Hell (Black Sabbath album)|Heaven and Hell]]'' was released on 25 April 1980, to critical acclaim. Over a decade after its release, AllMusic said the album was "one of Sabbath's finest records, the band sounds reborn and re-energised throughout".<ref>{{cite web|last=Prato|first=Greg|url=https://www.allmusic.com/album/heaven-and-hell-mw0000649895|title=Heaven and Hell – Review|website=AllMusic|access-date=9 February 2013}}</ref> ''Heaven and Hell'' peaked at number nine in the United Kingdom and number 28 in the U.S., the band's highest-charting album since ''Sabotage''. The album eventually sold a million copies in the U.S.,<ref name="riaa"/> and the band embarked on an extensive world tour, making their first live appearance with Dio in Germany on 17 April 1980.

Black Sabbath toured the U.S. throughout 1980 with Blue Öyster Cult on the "Black and Blue" tour, with a show at [[Nassau Coliseum]] in [[Uniondale, New York]], filmed for [[Don Kirshner's Rock Concert]]<ref>{{Cite web|url=https://simkl.com/tv/585810/don-kirshners-rock-concert/season-8/episode-13/|title=Don Kirshner's Rock Concert season 8 episode 13|access-date=10 November 2023}}</ref> and later released theatrically in 1981 as ''[[Black and Blue (video)|Black and Blue]]''.<ref>{{cite magazine|date=5 January 1981 |title=Brief Reviews: New Films |magazine=New York Magazine |volume=14 |issue=1 |page=72 |issn=0028-7369}}</ref> On 26 July 1980, the band played to 75,000 fans at a sold-out [[Los Angeles Memorial Coliseum]] with [[Journey (band)|Journey]], [[Cheap Trick]] and [[Molly Hatchet]].<ref>{{cite magazine|date=9 August 1980 |title=Stadiums & Festivals |magazine=Billboard |volume=92 |issue=32 |page=34 |issn=0006-2510}}</ref><ref>{{Cite web|url=https://www.black-sabbath.com/tourdates/hh_tour/|title=Heaven & Hell Tour – Black Sabbath Online|website=Black-sabbath.com|access-date=15 July 2021}}</ref> The next day, the band appeared at the 1980 [[Day on the Green]] at [[Oakland Coliseum]]. While on tour, Black Sabbath's former label in England issued a live album culled from a seven-year-old performance, titled ''[[Live at Last (Black Sabbath album)|Live at Last]]'' without any input from the band. The album reached number five on the UK chart and saw the re-release of "Paranoid" as a single, which reached the top 20.<ref name="billboard_200"/>

On 18 August 1980, after a show in [[Bloomington, Minnesota]], Ward quit the band. "It was intolerable for me to get on the stage without Ozzy. And I drank 24 hours a day, my alcoholism accelerated". Butler stated that after Ward's final show, the drummer came in drunk, stating that "he might as well be a Martian". Ward then got angry, packed his things and got on a bus to leave. Following Ward's sudden departure, the group hired drummer [[Vinny Appice]].<ref>{{cite web|title=Vinny Appice Interview|url= http://musiclegends.ca/interviews/vinny-appice-interview-black-sabbath/|publisher=Music Legends|access-date=6 May 2013|date= 7 March 2012}}</ref> Further trouble for the band came during their 9 October 1980 concert at the [[UW–Milwaukee Panther Arena|Milwaukee Arena]], which degenerated into a riot that caused $10,000 in damages to the arena and resulted in 160 arrests. According to the Associated Press: "The crowd of mostly adolescent males first became rowdy in a performance by the Blue Oyster Cult" and then grew restless while waiting an hour for Black Sabbath to begin playing. A member of the audience threw a beer bottle that struck Butler and effectively ended the show. "The band then abruptly halted its performance and began leaving" as the crowd rioted.<ref>{{Cite web|url=https://news.google.com/newspapers?nid=ddB7do2jUx8C&dat=19801010&printsec=frontpage|title=Spokane Daily Chronicle – Google News Archive Search|website=News.google.com|access-date=15 July 2021}}</ref>

The band completed the ''Heaven and Hell'' world tour in February 1981 and returned to the studio to begin work on their next album.<ref name="R2460156B">{{cite AV media notes |title=Mob Rules |others=Black Sabbath |year=1981 |first=Bryan |last=Reesman |pages=2–9 |type=CD booklet; 2008 reissue |publisher=Warner Bros./Rhino |id=R2 460156 B |location=Burbank, California}}</ref> Black Sabbath's second studio album that was produced by [[Martin Birch]] and featured Ronnie James Dio as vocalist, ''[[Mob Rules (album)|Mob Rules]]'', was released in October 1981 and was well received by fans, but less so by critics. ''Rolling Stone'' reviewer J. D. Considine gave the album one star, claiming "''Mob Rules'' finds the band as dull-witted and flatulent as ever".<ref>{{cite magazine|last=Considine |first=J.

A decade after its release, AllMusic's Eduardo Rivadavia called ''Mob Rules'' "a magnificent record".<ref>{{cite web|last=Eduardo|first=Rivadavia|url=https://www.allmusic.com/album/mob-rules-mw0000194116|title=Mob Rules – Review|website=AllMusic|access-date=9 February 2013}}</ref> The album was certified Gold<ref name="riaa"/> and reached the top 20 on the UK chart. The album's title track, "The Mob Rules", which was recorded at [[John Lennon]]'s old house in England,<ref name="R2460156B" /> was also featured in the 1981 animated film ''[[Heavy Metal (film)|Heavy Metal]]'', although the film version is an alternate take and differs from the album version.<ref name="R2460156B" />

Unhappy with the quality of 1980's ''[[Live at Last (Black Sabbath album)|Live at Last]]'', the band recorded another live album – titled ''[[Live Evil (Black Sabbath album)|Live Evil]] –'' during the ''Mob Rules'' world tour, across the United States in [[Dallas]], [[San Antonio]] and [[Seattle]], in 1982.<ref>{{cite AV media notes |title=Live Evil |others=Black Sabbath |year=1983 |chapter=Mob Rules World Tour 1981–1982 |first=Hugh |last=Gilmour |pages=3–5 |type=CD booklet; 1996 reissue |publisher=Gimcastle/Castle Communications |id=ESM CD 333 |location=England}}</ref> During the mixing process for the album, Iommi and Butler had a falling-out with Dio. Misinformed by their then-current mixing engineer, Iommi and Butler accused Dio of sneaking into the studio at night to raise the volume of his vocals.<ref>{{cite web|last=Marszalek|first=Julian|title=Black Sabbath's Tony Iommi Recalls the ''Heaven and Hell'' Era|url=http://www.spinner.com/2010/04/02/black-sabbath-tony-iommi-interview/|archive-url=https://web.archive.org/web/20120320015547/http://www.spinner.com/2010/04/02/black-sabbath-tony-iommi-interview/|url-status=dead|archive-date=20 March 2012|publisher=spinner.com|access-date=26 January 2019}}</ref> In addition, Dio was not satisfied with the pictures of him in the artwork.<ref>{{cite news |last=Goodman |first=Dean |title=Black Sabbath reunites without Ozzy |url=http://www.news.com.au/story/0,23599,20648014-1702,00.html |date=26 October 2006 |work=[[News Limited]] |archive-url=https://web.archive.org/web/20091026184906/http://www.news.com.au/story/0%2C23599%2C20648014-1702%2C00.html |archive-date=26 October 2009 |access-date=13 May 2008 |url-status=dead}}</ref> Butler also accused Dio and Appice of working on a solo album during the album's mixing without telling the other members of Black Sabbath.<ref>{{cite magazine|last=Welch|first=Chris |author-link=Chris Welch |title=London Calling|magazine=Record|date=June 1983|volume=2|issue=8|page=4}}</ref> "Ronnie wanted more say in things", Iommi said. "And Geezer would get upset with him and that is where the rot set in. ''Live Evil'' is when it all fell apart. Ronnie wanted to do more of his own thing, and the engineer we were using at the time in the studio didn't know what to do, because Ronnie was telling him one thing and we were telling him another. At the end of the day, we just said, 'That's it, the band is over'".{{sfn|Rosen|1996|p=118}} "When it comes time for the vocal, nobody tells me what to do. Nobody! Because they're not as good as me, so I do what I want to do", Dio later said. "I refuse to listen to ''Live Evil'', because there are too many problems. If you look at the credits, the vocals and drums are listed off to the side. Open up the album and see how many pictures there are of Tony, and how many there are of me and Vinny".{{sfn|Rosen|1996|pp=107–108}}

Ronnie James Dio left Black Sabbath in November 1982 to start [[Dio (band)|his own band]] and took drummer Vinny Appice with him. ''Live Evil'' was released in January 1983, but was overshadowed by Ozzy Osbourne's Platinum-selling album ''[[Speak of the Devil (Ozzy Osbourne album)|Speak of the Devil]]''.<ref name="riaa"/>
