Yes, it's Black Sabbath legend Tony Iommi! At age 17, Iommi was involved in an industrial accident that cost him the tips of two of his fingers, but he overcame that obstacle to become the master of the metal riff.

For over four decades now, Iommi has been the only constant member of the mighty Black Sabbath, presiding over a revolving door of bandmates that took us about a week to fully sort out.

At the end of 2011, the group's original lineup announced they would get together for a reunion tour and album. The process was temporarily derailed when the guitarist was diagnosed with lymphoma -- and became a 3/4 reunion when drummer Bill Ward left over money issues. But in typical "can-do" fashion Iommi kicked cancer's ass, helped deliver the well-received '13' album and began touring all over the world again.
