Joel McIver's acclaimed Black Sabbath biography, Sabbath Bloody Sabbath, concluded in 2011 that its subjects were at a crossroads. Could Ozzy, Tony, Geezer and Bill manage after over 40 years in business to get back together one more time? After all, the veteran heavy metal musicians were grieving for their fallen comrade Ronnie James Dio and about to face a devastating medical diagnosis for one of their own. McIver's brand-new, updated volume brings the story up to date with the tale of Sabbath's near-miraculous return to form with the Rick Rubin-produced 13 album, which topped charts worldwide on its release in 2013. In true Sabbath style, however, nothing went entirely to plan, with internal arguments, last-minute band-member replacements -- and a genuine fear that this may be Sabbath's very last shot at glory.

Joel McIver is the author of more than 20 books on music including biographies of Rage Against The Machine, Metallica, Slayer and Machine Head. He contributes to several British and American music and film magazines and often appears on radio and TV. More info: www.joelmciver.co.uk.
