context_page_description: Black Sabbath were an English rock band formed in Birmingham in 1968 by guitarist Tony Iommi, drummer Bill Ward, bassist Geezer Butler and vocalist Ozzy Osbourne. They are often cited as pioneers of heavy metal music. The band helped define the genre with releases such as Black Sabbath, Paranoid, and Master of Reality. The band had multiple line-up changes following Osbourne's departure in 1979, with Iommi being the only constant member throughout its history.
  After previous iterations of the group called the Polka Tulk Blues Band and Earth, the band settled on the name Black Sabbath in 1969. They distinguished themselves through occult themes with horror-inspired lyrics and tuned-down guitars. Signing to Philips Records in November 1969, they released their first single, "Evil Woman" in January 1970. Their debut album, Black Sabbath, was released the following month. Though it received a negative critical response, the album was a commercial success, leading to a follow-up record, Paranoid, later in 1970. The band's popularity grew, and by 1973's Sabbath Bloody Sabbath, critics were starting to respond favourably.
context_section_description: Sharon Arden (later Sharon Osbourne), daughter of Black Sabbath manager Don Arden, suggested former Rainbow vocalist Ronnie James Dio to replace Ozzy Osbourne in 1979. Don Arden was at this point still trying to convince Osbourne to rejoin the band, as he viewed the original line-up as the most profitable. Dio officially joined in June, and the band 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."
  Geezer Butler temporarily left the band in September 1979 for personal reasons. According to Dio, the band initially hired Craig Gruber (with whom Dio had previously played while in Elf) on bass to assist with writing the new album. Gruber was soon replaced by Geoff Nicholls of 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 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". Heaven and Hell peaked at number 9 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., 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 and released theatrically in 1981 as Black and Blue. On 26 July 1980, the band played to 75,000 fans at a sold-out Los Angeles Memorial Coliseum with Journey, Cheap Trick, and Molly Hatchet. 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 without any input from the band. The album reached number five on the British charts, and saw the re-release of "Paranoid" as a single, which reached the top 20.
  On 18 August 1980, after a show in Minneapolis, 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". Geezer 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.  Further trouble for the band came during their 9 October 1980 concert at the Milwaukee Arena, which degenerated into a riot causing $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 bassist Butler and effectively ended the show. "The band then abruptly halted its performance and began leaving" as the crowd rioted.
  The band completed the Heaven and Hell world tour in February 1981, and returned to the studio to begin work on their next album. Black Sabbath's second studio album produced by Martin Birch and featuring Ronnie James Dio as vocalist Mob Rules was released in October 1981, to be well received by fans, but less so by the critics. Rolling Stone reviewer J. D. Considine gave the album one star, claiming "Mob Rule
