Anthony Frank Iommi (/aɪˈoʊmi/) (born 19 February 1948) is a British musician. He co-founded the pioneering heavy metal band Black Sabbath, and was the band's guitarist, leader and primary composer and sole continuous member for nearly five decades. Iommi was ranked number 25 in Rolling Stone magazine's list of the "100 Greatest Guitarists of All Time". On his last day of work in a sheet metal factory, as a teenager, Iommi lost the tips of the middle and ring fingers of his right hand in an accident, an event which crucially impacted his playing style. He briefly left Black Sabbath (then known as Earth) in 1968 to join Jethro Tull, but did not record any material with the band, and subsequently returned to Black Sabbath in 1969. In 2000, he released his first solo album Iommi, followed by 2005's Fused, which featured his former bandmate Glenn Hughes. After releasing Fused, he formed Heaven & Hell, which disbanded shortly after the death of Ronnie James Dio in 2010 (they toured on Black Sabbath songs when Dio was in the band but changed the name for legal reasons). In 2011, Iommi published his autobiography, entitled Iron Man: My Journey Through Heaven and Hell with Black Sabbath.
