METALLICA singer/guitarist James Hetfield turns 56 years old on Saturday (August 3). Born in 1963 in Downey, California, James was the son of a truck driver named Virgil and a singer named Cynthia. Hetfield's parents were Christian Scientists and strongly disapproved of the use of any kind of medicine or medical treatments, even when Cynthia was dying of cancer in 1979. This upbringing inspired many of METALLICA's later songs, such as "The God That Failed". Hetfield also had two older half-brothers from his mother's first marriage and a younger sister.

According to The Pulse Of Radio, Hetfield took up piano at the age of nine and began playing guitar at 14. He was in bands called LEATHER CHARM and OBSESSION during his teen years. In October 1981 he answered a classified ad placed in a local paper called Recycler by Danish drummer Lars Ulrich, and METALLICA was born.

Hetfield told The Pulse Of Radio he still recalls the group's first gig, with original lead guitarist Dave Mustaine. "First METALLICA show was at Radio City in Anaheim. I remember the first song we played, Dave broke a string, and I was stranded up there. I was just singing, I wasn't playing guitar back then, and I was so uncomfortable, I was like, 'So, how's it going...' There were about 200 people. You know, your first gig, everyone shows up. Second gig, there's about 20, you know. [laughs]"

Solidifying the lineup with bassist Cliff Burton and lead guitarist Kirk Hammett, who replaced Mustaine, METALLICA signed to Megaforce Records in 1983 and released its debut album, "Kill 'Em All", in July of that year, while also relocating from the Los Angeles area to San Francisco.

Pioneers and leaders of the underground speed metal movement, METALLICA signed with major label Elektra Records in 1984 just as they released their sophomore album, "Ride The Lightning".

Hetfield told The Pulse Of Radio how the scene in San Francisco at the time exploded thanks to METALLICA's success. "Well, I recall on the (1984) 'Ride The Lightning' tour, after coming back, coming back home and feeling like the scene has grown so big. And, you know, we came back, we had our 'Ride The Lightning' shirts and things are kind of going good for us, 'Yeah, we just went on our second tour,' and we come back and the scene has gotten so much bigger."

Weathering the death of Cliff Burton in a tour bus accident in 1986, METALLICA became bigger and bigger, scoring their first gold album with 1986's "Master Of Puppets" and their first platinum disc with 1988's "…And Justice For All". The group became superstars in 1991 with the release of the self-titled "black album," which has sold over 15 million copies to become the biggest selling album of the SoundScan era of sales tracking.

It was during the late '90s that cracks began to show in both METALLICA's public image and Hetfield's tough-guy demeanor. Always a heavy drinker, his alcohol intake reached toxic levels in 2001 just as the band was starting work on its eighth studio album.

He recalled the moment when he made the decision to get help for his problems with drugs and alcohol. "My wife threw me out of the house and I went to rehearsal, and she could not believe that I had done that, and said, 'You've got to check yourself in somewhere,' and I said, 'Nah, no way, I'm the singer for METALLICA, I can't get help. I don't need help,'" he said. "A lot of denial. She was very adamant about me seeking the help and I went in, I think, for her and for my family."

Hetfield said that entering rehab was one of the scariest times in his life. "I was just kind of really scared," he said. "I was dropped off into this place and at that point my family was in question. Basically the family had split up, or I was no longer in the house, and it was totally one of the most scary times in my life. It was really like the earth was shaking under me, there was no stability, it felt like a constant earthquake. I had no idea what I was doing, where I was going."

Hetfield got clean and sober in 2002, returning to METALLICA to record the controversial "St. Anger" album and make the documentary "Some Kind Of Monster", which chronicled his struggle as well as the band's near-breakup.

Hetfield told The Pulse Of Radio at the time that he was okay with people seeing that side of his life. "Connecting with people has never been easy for me. I think the more that people know about me and my struggles, the easier it will be to connect with people. I've put myself out there, and if they choose to stomp on my heart, or to embrace it, that is up to them."

While "St. Anger" received a mixed reaction from fans, the band came back full force with 2008's "Death Magnetic". Hetfield told The Pulse Of Radio at the time that having gone through all its turmoil, METALLICA was stronger than ever. "You know, 'St. Anger', the 'Monster' movie, all the stuff that we went through — once we got back together and started playing again, we knew that we were given some sort of gift to continue and not fall like many other bands have. So we've got to take care of this, and we're doing our extra best to do that."

Hetfield and the band are busier than ever, having spent the last three years touring in support of their latest album, "Hardwired… To Self-Destruct", which came out in November 2016.
