James Hetfield and Cali Hetfield Deliver Haunting Acoustic Duet at Acoustic-4-A-Cure 2016
In May 2016, a crowd gathered at The Fillmore in San Francisco for the annual Acoustic-4-A-Cure concert, expecting raw, intimate performances from some of rock’s biggest names. But few anticipated the emotional highlight of the night: a stripped-down, spellbinding duet between Metallica frontman James Hetfield and his daughter, Cali Hetfield.
Performing the soulful classic “I Put a Spell on You,” originally by Screamin’ Jay Hawkins and famously covered by Annie Lennox, the father-daughter duo stunned the audience with a performance that was equal parts eerie, elegant, and deeply human. James, known for his gritty vocals and heavy guitar riffs, stepped into a different light—trading distortion for warmth, and fire for feeling.
As he gently strummed his acoustic guitar, Cali took the lead with a vocal maturity far beyond her years. Her voice was clear, emotional, and haunting, wrapping around the melody with surprising confidence. James provided soft harmonies and a grounding rhythm, allowing Cali to soar in the spotlight while still anchoring the performance with his quiet presence.

This rare public appearance by Cali marked a touching family moment on stage—and for many, revealed a new side of Hetfield not often seen under the harsh glare of Metallica’s stadium lights. The chemistry between father and daughter was undeniable, and their performance quickly went viral online, celebrated by fans for its authenticity and heart.
Acoustic-4-A-Cure, co-founded by Sammy Hagar and James Hetfield, raises money for pediatric cancer research. But on that night, the cause was not the only thing moving the audience—what moved them was a fleeting, fragile glimpse into the life of a rock legend, not as a frontman, but as a father.

Years later, the performance remains one of the most memorable in the event’s history, not because of theatrics or fame—but because of the quiet, powerful connection it captured between two generations, bound by music and something even deeper.
