Black Sabbath – "Iron Man"

(1971 – Included on the album "Paranoid", Vertigo/Warner, 1970)

I am iron man

Eight strokes of Bill Ward's kick drum, dry, slow, minimal and mechanical, introduce one of the most famous, important and influential guitar riffs of all time: the thickest string on Tony Iommi's electric guitar, the low E, held down past the end of the fretboard and then released, making it emit a menacing metallic wail to pair with Ozzy Osbourne's filtered, robotic, inhuman voice — legend has it achieved by singing through the blades of a fan, but more likely the result of very intense use of the ring-modulator.

In under thirty seconds, "Iron Man", the single released on 7 October 1971 by the English band Black Sabbath, proves itself an unforgettable track, so eccentric it could be called one of a kind. And speaking of kind: already in this scant half-minute, it's clear something different is going on compared to "Evil Woman", the Crow song the band used as their first single, back in January 1970. Of the blues roots, in this mechanical beat, in the monstrously distorted guitar, in the android voice, nothing remains. But "Iron Man" is much more than a departure from the blues and its younger sibling blues-rock, still present in good measure on the masterpiece "Black Sabbath", because together with a handful of other essential tracks it helps define the boundaries dividing hard rock — the label under which the legendary debut by the four Birmingham musicians at least partly falls — from heavy metal. After all, there can be nothing more metallic than an iron man, you'll have to agree.

Jokes aside, "Iron Man" is a track that, already in its famous opening, tells us of a marked shift that took place in the history of rock, one that can essentially be summed up as a move away from the emotional and aesthetic imprint of the blues. The blues has no room for anything mechanical or artificial; instead it favors a narrative made of blood, sweat and tears. Where the blues tells of one's own lived experience, here we are deep in science-fiction storytelling, an adventure involving time travel, magnetic storms, plot twists and tragic deaths.

Let's first reconstruct how "Iron Man" came to be released as a single, before exploring the rest of the track. The already-mentioned debut album was released on Friday 13 February 1970 — obviously not a random date for pranksters like Ozzy and co. — and met with considerable success in Britain and the United States, despite the opposition of many critics, including the famous Lester Bangs, who harshly criticized aspects of it that would later become exactly what so many metalheads came to love. The band went back into the studio in June 1970, wanting to call the second album "War Pigs", but ultimately opted for "Paranoid", following a short track written, according to Bill Ward, in 20-25 minutes during the sessions and perfectly suited to serve as a calling card for a wider audience, given its simple structure and short length combined with towering volume. It would remain their biggest hit single at home and a solid hit in the United States, perhaps their most mainstream track, but it still has the flaw of not properly representing the most significant developments taking place in the band's style, which was in fact growing ever more comfortable with long, heavy, complex songs, and certainly not with short, armor-plated, if catchy, rock'n'roll numbers.

As much as "Paranoid" is itself a classic, a reference model for a certain style of heavy metal in England, it isn't even close to being the most visionary and ambitious track on the record.

The aforementioned "War Pigs" is a great example of where the band was heading: nearly 8 minutes long, distorted guitar riffs in abundance, long instrumental excursions and expansive psychedelic explorations. The other track on "Paranoid" that captures this evolution, fundamental for all of hard rock and heavy metal, is "Hand Of Doom", 7 minutes that helped name an entire subgenre and that make adventurous songwriting their strong point, along with a novel way of using compositional space by exploiting the contrast between fullness and emptiness, explosion and desolation.

With these tracks freshly released at home, Black Sabbath also arrive in the United States in October 1970, but to avoid cannibalizing the success of their debut, they delay the release of the "Paranoid" album overseas: it will only reach American shores in January 1971.

To help promote the early tours, releasing a second single comes in handy, and so it happens that "Iron Man" becomes the English band's first modestly successful single in the US: it reaches number 52 on Billboard, and it would take until "Psycho Man" in 1998 to do better. In England the single isn't even released, remaining an exclusive for Canada and the US.

It's a strange story, but somehow "Iron Man" makes its way into American rock history, helping "Paranoid" become a quadruple-platinum album in the United States and platinum in Canada, while at home it stalls at gold. The single version, trimmed to 3:33 and cut in its second half, is however lesser than the album version, which we had begun to describe and which remains our reference for the rest of this feature. After the iconic opening, a five-chord riff arrives, deafening and cadenced, answered by a second, slightly more elaborate riff section, creating the track's fundamental framework and definitively cementing its heavy metal style: it's a manifesto of sonic power, a slow and colossal step, gripping and deafening.

After the dissonant wail and the driving riff, the track also begins to develop narratively, following up on the clues already given to the listener at the start. We thus discover that Geezer Butler, bassist and lyricist, decided to tell an extravagant science-fiction adventure, with apocalyptic implications and a surprising narrative twist.

The robotic-voiced being from the opening raises many questions among the people who encounter him: they wonder if he's mad, if he can see, or if he can even walk without falling, whether we should consider him alive or dead, and ultimately whether we should pay him any attention or simply not worry about him. These are two quatrains that actually deepen the sense of mystery, intriguing more than explaining, and compelling us to keep listening, if only to satisfy our own curiosity.

The third and fourth verses are the crucial ones for understanding who the iron man of the title really is. We discover that he was an individual like us, who managed to travel through space and glimpse humanity's future, receiving in return a menacing apocalyptic vision. On the journey back to Earth, he passes through a powerful magnetic field, somehow transforms into a heavy metal being, and remains trapped in his now-alien body, profoundly different from when he set off. People, far from taking pity on his condition as a metal monster incapable even of communicating his terrible prediction about the future, neglect him, if not outright mock him, until they stir in him a deep desire for revenge: the humanity he wanted to save from a hostile future is the very same humanity for which he now seeks a terrible, bloody punishment.

After three minutes, that "Now he has his revenge" represents the narrative plot-twist and is accompanied by a shift in the music itself as well: the slow pace becomes a ride of blistering blues-rock and then a guitar barrage that then leads back, with renewed power, to the driving riff, slow and heavy as the iron man's footsteps.

The time has come, and the strange metallic being is ready to unleash his rage on the people he had wanted to save, who now become his chosen victims. Precisely because he received no attention or help, he has plotted his terrible revenge.

Ultimately, the metallic protagonist who screams his name at the outset becomes the cause of the apocalypse he had glimpsed in the future, making "Iron Man" a curious example of a self-fulfilling prophecy.

After 4 minutes and 20 seconds, having closed the final verse with a superhero-like proclamation like "Iron man lives again", the track prepares for its explosive finale. The tempo surges, Butler and Ward duel in a supersonic head-to-head that serves as a feverish sonic canvas on which Iommi can unleash the full power of his guitar, first returning to the metallic blows of the opening, then weaving an epic, Morricone-esque theme that spins on itself several times, before coming to a decisive stop in one last, heart-stopping coup de theatre.

"Iron Man" experienced a second youth thanks to the famous 2008 Marvel film of the same name, in which it was featured over the end credits, even though the parallel with the comic-book hero stops at the name. The TV channel VH1 named it the greatest heavy metal song of all time, one of those decisions that even those who disagree would struggle to argue against. Black Sabbath have since released 17 more albums, the last of which, in 2013, closed out their career. For their final concert, on February 4, 2017 in their hometown of Birmingham, they had to select 17 songs from a career spanning over forty years, and among them, "Iron Man" simply couldn't be left out.

Has he lost his mind?

Can he see or is he blind?

Can he walk at all

Or if he moves will he fall?

Is he alive or dead?

Has he thoughts within his head?

We’ll just pass him there

Why should we even care?

He was turned to steel

In the great magnetic field

When he traveled time

For the future of mankind

Nobody wants him

He just stares at the world

Planning his vengeance

That he will soon unfurl

Now the time is here

For iron man to spread fear

Vengeance from the grave

Kills the people he once saved

Nobody wants him

They just turn their heads

Nobody helps him

Now he has his revenge

Heavy boots of lead

Fills his victims full of dread

Running as fast as they can

Iron man lives again

Ride the wave of great music
