How Ronnie James Dio's Voice Broke a Vintage Mic During His Tenacious D Cameo

During the recording of "Kickapoo" for Tenacious D's "The Pick of Destiny," Ronnie James Dio's immense vocal power reportedly broke a high-end vintage microphone on the first take. The session was saved when they used the personal mic Dio, ever the professional, had brought with him.

How Ronnie James Dio's Voice Broke a Vintage Mic During His Tenacious D Cameo

In the pantheon of rock and roll, there are stories that sound too perfect to be true, crystallizing an artist's entire persona into a single, legendary moment. One such tale involves the inimitable Ronnie James Dio, a vocalist whose power was so immense it could, quite literally, break the very technology meant to capture it. The stage for this event was an unlikely one: a cameo performance for the comedy-rock duo Tenacious D.

An Iconic Collaboration

In 2006, Jack Black and Kyle Gass of Tenacious D were creating their magnum opus, the rock opera film "Tenacious D in The Pick of Destiny." The film's opening number, "Kickapoo," required a voice of god-like authority to play the part of a rock-and-roll-hating father who is secretly a demon in disguise, sending a young Jack Black on his epic quest. There was only one man for the job: Ronnie James Dio. Dio, a titan of heavy metal known for his soaring vocals in bands like Rainbow, Black Sabbath, and his own eponymous band, was a hero to Black and Gass. His agreement to participate was a dream come true, but no one could have predicted how memorable the recording session would become.

The Voice vs. Vintage Tech

According to an account from Jack Black, the studio's producer insisted on using the best equipment for the legendary vocalist. A beautiful, expensive, and notoriously delicate vintage Telefunken microphone was set up to capture Dio's voice. These microphones are revered for their warmth and sensitivity, capable of picking up the most subtle nuances of a performance. However, they were not designed for the sheer, uncompressed power that Dio was about to unleash. On his very first take, Dio leaned into the microphone and sang his lines with the full force of his legendary lungs. The result? The microphone gave out instantly. As Black tells it, Dio's voice "blew out the diaphragm" of the pricey vintage gear, rendering it useless.

A Lesson in Professionalism

While the production team may have been momentarily panicked, Dio was not. Ever the seasoned professional, he had come prepared. He calmly informed the team that he had brought his own microphone and retrieved his personal, battle-tested Shure SM58. The SM58 is the polar opposite of a delicate vintage Telefunken; it is famous in the music world for its near-indestructibility and is the industry standard for live vocal performances precisely because it can handle extreme volume levels without distortion or damage. As one audio enthusiast noted in an online discussion of the event:

>I think most experienced metal singers know that they should use a SM58 or something similar for recording. The sound engineers are always like 'No! This mic is better and much more expensive' but in the end the 58 just works better.

The session continued with Dio's personal mic, and the powerful vocals on the final track are a testament to its capability. The incident perfectly illustrates the chasm between sensitive studio technology and the raw reality of a world-class metal vocalist. More importantly, it highlights Dio's deep understanding of his own craft. He knew the force of his instrument—his voice—and had the experience to know exactly what tool was required to handle it. It was a quiet display of professionalism that spoke volumes.

A Legacy Larger Than Life

The story of the broken microphone has become a beloved piece of rock folklore, a tangible metaphor for Ronnie James Dio's monumental talent. It wasn't just about volume; it was about a lifetime of honed power and the wisdom of a master craftsman who always brought his own tools. It was a moment where the legend became undeniably real, proving that some voices are simply too powerful for this world's more delicate machinery.
