Nineteen thousand people inside The Forum went from roaring to breathless in an instant.
Jack Black had stepped onto the stage. No guitar. No backing band.
Just his voice cutting through the space, steady and clear. The energy shifted, like everyone knew they were about to see something that wasn’t on the program.
He scanned the crowd, then found himself locking eyes with James Hetfield. Comedy and thrash metal don’t usually meet in the same breath, but in that room, they collided. Black cracked a quick joke, the kind that draws out a ripple of awkward laughter. Then, without warning, he let out a raw, guttural call — “Spoonman!” It wasn’t just a song cue. It felt like a name pulled from somewhere deep, a call that carried Chris Cornell’s memory straight into the air.
This was January 16, 2019, at “I Am the Highway: A Tribute to Chris Cornell.” The concert had already been a night of legends — Metallica, Foo Fighters, members of Soundgarden and Audioslave. But no one expected this pairing.

Black had walked out between sets to keep the crowd engaged while the next act set up. He spoke with warmth and a touch of mischief about Cornell, calling him a singer “who could hit notes that didn’t even exist yet.” Halfway through his playful spin on Soundgarden’s “Spoonman,” Hetfield simply appeared beside him. No announcement. No grand build-up. The crowd roared as they launched into an off-the-cuff version of Metallica’s “One,” stripped of all its usual polish.
It wasn’t flawless. It didn’t have to be. The jam was loose, imperfect, and deeply human — exactly what a tribute should be when the person being honored was known for heart over spectacle.
The rest of the lineup kept the stage electric. Miley Cyrus, Josh Homme, Fiona Apple, and others shared their takes on Cornell’s work. But this moment with Black and Hetfield stood apart. For a few minutes, it didn’t feel like a concert. It felt like friends remembering someone they all respected, and letting the music carry that feeling.
Clips of the performance spread quickly afterward. Fans called it one of the night’s most genuine moments — not because it was rehearsed or technically sharp, but because it wasn’t. It was a collision of two very different worlds, held together by respect for one man’s voice.
“He sang notes that didn’t even exist yet,” Black told the crowd. “He was a master… and tonight, we celebrate that.”
Chris Cornell had a way of bringing people together who might never have crossed paths otherwise. That night, a comedian and a metal icon proved it again.
