UAWIL #13: Black Sabbath - The Dio Years

At the end of the 70s, Black Sabbath had lost their way.  The excess of the decade and the departure of Ozzy Osbourne left the future of the band in limbo.  However, after the addition of American powerhouse Ronnie James Dio on vocals, the band was reborn and came back with two classic albums - Heaven & Hell and Mob Rules.
