During a new interview with Metal Hammer, Metallica drummer Lars Ulrich has shared a little-known truth about the lyrics of their debut album, Kill Em’ All.

He said that lyrics of Metallica’s early years were full of sexual connotations. He talked on “The Four Horsemen”, and said:

“Dave brought in some things he had from his old band, Panic – things he’d been jamming, bigger-picture ideas, stuff like that.

The song ‘The Four Horsemen was,’ in its early version, called ‘Mechanix,’ and it was literally a song about sex. There were lyrics about taking the hose and sticking it in the tank – a gas-station stop disguised as sexual engagement.

It didn’t make a lot of sense to me at the time, but we knew that was the sort of thing we wanted to move away from – the sexual stuff that hard rock bands were singing about at the time, which we thought was a little light and a little obvious.

You didn’t find stuff like that on the first Witchfynde album [1980’s ‘Give ‘Em Hell’].”

Interviewer asked:

“Was the music you were making a reaction to everything else that was happening in rock and metal at the time?”

Lars responded:

When you talk about Metallica during that time period, you have to use the word ‘contrary.’ It’s not so much what turns you on as what turns you off. You often went: ‘We definitely don’t like that, so we’re gonna do this.’

We didn’t want to be this, we didn’t want to do that, we didn’t want to do what the American bands were doing, we didn’t want to write this particular way. We were finding our own voice.”

On Phantom Lord, Lars said:

“That song was like ‘Mechanix,’ in that it originally had sexual connotations to it. But that’s who Dave Mustaine was. He was cool and confident, he had a cool haircut.

When we went and hung out with him at his apartment, there were girls there. He was much more of a man of the world, where James and I were these weird little awkward, disenfranchised teenagers.”
