For more than three decades, rock fans have hoped for the return of Black Sabbath—Ozzy Osbourne, Tony Iommi, and Geezer Butler—but few could have predicted the forceful return-to-form of 13, produced by seven-time GRAMMY®-winning producer Rick Rubin. The band that defined heavy metal picks up immediately where they left off, delivering sprawling songs (five of them are over seven minutes) that possess every ounce of the maniacal vitality of their trailblazing work in the '70s. On 13, Sabbath is joined by drummer Brad Wilk (Rage Against The Machine) on such epic songs as “End of the Beginning,” "Loner," "Dear Father," and "Age of Reason." 13 is a testament to the enduring relevance of Black Sabbath's long-running reign.
