One week before it's initial release, Black Sabbath's new album '13', is streaming in its entirety on iTunes.

The latest effort from the most of the original line-up is the first such in over 30 years. Original drummer Bill Ward is the only member from the first inception of the band not to lend his thunder to the music. However, Rage Against The Machine's Brad Wilk fits nicely into their sound. Rick Rubin is producing and lending his guidance to the band of hard-rock minstrels.

The album features 11 new original tracks, including the recent release and hard-rock radio hit God Is Dead?
