Black Sabbath

The three-fourths of the original Black Sabbath lineup—Ozzy Osbourne, Tony Iommi and Geezer Butler, minus drummer Bill Ward—issued a highly impressive Rick Rubin–helmed comeback, 13, in 2013, followed by a multi-leg world tour. Now, the first and greatest heavy-metal band, plus fill-in drummer Tommy Clufetos, hits the road for what it claims will be its final trek. Prepare to tremble before immortal classics such as "Black Sabbath" and "Iron Man," and hear a few of the new joints as well.
