Heavy metal pioneers Black Sabbath return to the top to the Rock and Roll heap with album 13. Their latest release debuted at first place on the Billboard chart. Promoting the album with a world tour that begins stateside, Ozzy and company are back to restore the reputation of Black Sabbath. After a blistering beginning in 1968, and horrid separation in 1978, the band returns to the sound they created, and are blasting it to the next level. Originally calling themselves Earth, the name Black Sabbath was inspired by the same 1963 Boris Karloff film. Their debut album was released on Friday the 13th, 1970. The bands style is infamous for dark topics of war, social chaos, supernatural and the afterlife. Paranoid followed with the notable Iron Man. The album was very successful, despite virtually no radio play. Master of Reality was released only months later with a world tour that fatigued the group. Moving to Los Angeles to record, Volume 4 followed just months later, achieving gold status in less than a month. The band returned to England continuing their existence in a haunted castle in Wales. November 1973 saw the release of the critically acclaimed Sabbath Bloody Sabbath. A 1974 world tour followed with the band playing to huge audiences. Sabotage, released in 1975, sought to shed the synthesizers and get back to their metal roots. The Sabotage tour was cut short due to an Ozzy motorcycle accident which injured his back. Technical Ecstasy, released in September 1976, featured more synthesizers and less doom, but failed to inspire record sales. After the 1977 tour, Ozzy quit the band, only to later return for work on Never Say Die! Following the 1978 tour, the group returned to Los Angeles, only to see Ozzy leave and replaced with Ronnie James Dio. The group released Heaven and Hell to critical acclaim in 1980 and Mob Rules in 1981. Thereafter, Dio sought out his own sound and fury. And in late 1982, Ozzy released his solo Speak of the Devil. Ian Gillian joined in 1983 for the Born Again album and tour. 1984 heard the vocals of Glen Hughes of Deep Purple and Trapeze fame. Hughes was replaced by Ray Gillen who soon departed for his own musical pursuit. Alliance vocalist Tony Martin arrived for Eternal Idol, Headless Cross, and Tyr. Ronnie James Dio returned for the Dehumanizer album and tour in 1992. Tony Martin returned for vocals on Cross Purposes which released in 1994 and Forbidden in 1995. Finally, the original lineup returned to stage for a couple of stadium shows in 1997, a year later released as the Reunion live album. Together again, they headlined Ozzfest in 1999, 2002, 2004, and 2005.
