The story behind the song: Iron Man by Black Sabbath

There’s a well-thumbed story that the meaning of Black Sabbath's Iron Man was inspired by the Marvel Comics character of the same name. But it’s not true. Although Marvel had established that superhero in 1963, Sabbath bassist Geezer Butler, who wrote the lyrics for the iconic song, had never even heard of him in 1970. 

“My parents never let me read American comics when I was growing up,” he says.
“I knew about Batman and Superman, but that’s about it. For me it was all about the Beano and the Dandy. So whenever someone’s said to me over the years: ‘Oh, didn’t you write this about the superhero?’, I’d just say: ‘Sorry, never heard of him.’” 

The idea for Iron Man (which first appeared on the second Black Sabbath album, Paranoid, released in 1970), actually started with Ozzy Osbourne.

“I can’t exactly recall what Ozzy said, but it was something like: ‘Why don’t we do a song called Iron Man, or maybe Iron Bloke’. That got me thinking about a lump of metal, and then putting it all into a science-fiction context. It all flowed from there.”

The meaning of the storyline – a self-fulfilment prophecy, mixed up with time travel – is actually quite complex. It’s about a man who goes into the future and witnesses the apocalypse. Going back to his own time, he encounters a rogue magnetic field, which turns him into a mute, steel creature. Unable to talk, he still tries to warn people about the impending end of the world, but is only mocked for his troubles. Angry and bitter, he eventually causes the devastation he’d warned everyone about. Ultimately the would-be hero becomes the villain.

“I was heavily into science fiction at the time,” Butler recalls of almost 50 years ago. “Remember, this was the era of the space race,” he says. “A lot of the stuff I was writing about was inspired by those sorts of stories. I was fascinated by what might happen to a man who’s suddenly transformed into a metal being. He still has a human brain, and wants to do the right thing, but eventually his own frustrations at the way humanity treats him drives this creature to taking extreme action. It’s almost a cry for help.

“What I always attempted to do with my science-fiction plots was to make these relevant to the modern world at the time,” Butler continues. “So I brought war and politics in. It was also an era when the whole issue of pollution was starting to get attention, and this affected my thinking quite a bit.”

Former Sabbath drummer Bill Ward reckons that, musically, the song was nothing like anything else the band had done up to that point: “For me, this is a special song for the band. It was just so different. As soon as you hear that ominous start, you know something’s building. For me, the drumming was a real challenge to get right in the studio. But it’s also a drummer’s dream to play.

“Technically, we had real problems getting it right in the studio,” Ward recalls. “The trouble was that the microphones available to us in 1970 just weren’t up to the task of capturing the power and depth of the sound. I played very loud back then, and wanted a powerful bass drum sound; that’s what the song needed. Yet all I could get was a dull thud. For Rodger [Bain, producer] and Tom [Allom, engineer], trying to make Iron Man work was so tough. In the end they did an excellent job under the circumstances. Today it would be so easy for a band to get the proper sound on a song like this, because the technology exists.”

Over the years, Iron Man has become not only one of the cornerstones of the Sabbath catalogue, but also credited as one of the most important songs in the history of metal. For Geezer Butler, it is perhaps the track that bests sums up the band.

“I really do feel that when you listen to Iron Man, what you’re getting is the essence of what made Black Sabbath such a special band,” he offers. “It’s fairly simple, yet also has a lot of depth. I’m very proud of what we achieved here.”

Bill Ward believes that the song’s stature has grown over the years, to the point where it has now gone beyond being just a great Sabbath song.

“In America, if you go to most sports events you’ll hear it at some point. It’s now a part of the culture of the country. People recognise it as soon as it starts up. It’s very musical, but also so theatrical. I think its popularity now is such that, in a way, it no longer belongs to Ozzy, Geezer, Tony [Iommi] and me, it’s now everyone’s song.”

In 2008, Iron Man received another boost when it was included in the movie of the same name, based on the Marvel Comics creation. That delighted Butler.

“It was a recognition of just how much the song means,” he says with pride. “When you have such a major film using it, then it does introduce it to a new generation, kids who perhaps aren’t aware of who Black Sabbath are but who might be tempted to go and check us out.

“I suppose, because of the film, there’s also gonna be those who see a tie-up between what I wrote 40 years ago and the comic-book character. So, here we go again.”

Sabbath released Iron Man as a single in 1971. Although it reached No.52 in America (nine places higher than Paranoid), in the UK it make no impact at all.

“I think it worked best at the time in the context of the album,” Ward says. “We never thought of ourselves as a singles band anyway. But, over the years, Iron Man has grown and grown. I don’t think we believed at the time that it would turn out to be so special. But that’s the beauty of what happens: it’s the fans who decided this was a great song.”

Malcolm Dome

Malcolm Dome had an illustrious and celebrated career which stretched back to working for Record Mirror magazine in the late 70s and Metal Fury in the early 80s before joining Kerrang! at its launch in 1981. His first book, Encyclopedia Metallica, published in 1981, may have been the inspiration for the name of a certain band formed that same year. Dome is also credited with inventing the term "thrash metal" while writing about the Anthrax song Metal Thrashing Mad in 1984. With the launch of Classic Rock magazine in 1998 he became involved with that title, sister magazine Metal Hammer, and was a contributor to Prog magazine since its inception in 2009. He died in 2021
