James Hetfield is an American musician, singer, and songwriter known for being the co-founder, lead vocalist, of the rock band Metallica. Metallica, influential American heavy metal band that, along with Slayer and Anthrax, developed the subgenre speed metal in the early and mid-1980s.
In 2001, the singer entered rehab during the recording of the heavy metal band's St. Anger to combat against "alcohol addiction." While drummer Lars Ulrich had a cocaine problem until 2008, frontman James Hetfield never touched coke or heroin. Alcohol was his drug of choice. But while his bandmates cooled off with the drinking as the years went on, Hetfield never slowed.
