While working in a 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. Iommi briefly left Black Sabbath (then known as Earth) in 1968 to join Jethro Tull, but did not record any material with the band, and he 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.
