The best Ronnie James Dio era Black Sabbath album is without a doubt Heaven And Hell from 1980.  It was the first time Ozzy Osbourne wasn't involved in a Sabbath project and Dio's presence brought much change to the band and it's sound.  This album was a huge hit with both fans and critics, and continues to be a fan fave, even to this day.  Let's roll the title for today's Vault track around 5:20pm, on the radio or on-line.
