Black Sabbath - 13
13 was the final studio album by the legendary heavy metal band Black Sabbath and featured the core line up of Ozzy Osbourne, Tony Iommi and Geezer Butler (the drums were handed by Brad Wilk of Audioslave). The album was originally released in June 2013 and reached number one both in the UK and US, a feat the band had never managed before. The band that defined heavy metal picked up immediately where they left off with eight sprawling songs (five of them over eight minutes in length) that possess every ounce of the maniacal vitality of the Grammy-winning, Rock and Roll Hall of Fame inductees' trailblazing work in the 70s. Songs such as "End of the Beginning", "Loner", "Dear Father" and "Age of Reason" reinforce 13's testament to the enduring relevance of Black Sabbath's long-running reign.
