He's the founding member, bassist, and primary lyricist of one of rock's most influential bands. Now, Black Sabbath's Geezer Butler has just dropped a memoir spilling all the tea of how it really went down. Into the Void: From Birth to Black Sabbath--And Beyond follows the band's early inception as a scrappy blues quartet through the struggles that led to the many lineup changes while touring around London's gritty clubs (Eric Clapton, Jimi Hendrix, Frank Zappa, and The Who). The memoir also details the creation of their unique and iconic heavy riffs, tuned-down guitars, and apocalyptic lyrics that helped create the genre of heavy metal as we know it--to commercial success, leading to more than 70 million record sales worldwide without ever losing their cool. LifeMinute editor-in-chief Joann Butler sat down with Geezer to talk all about it and more. This is a LifeMinute with Black Sabbath's Geezer Butler.
