James Hetfield of Metallica collaborates with his daughter for a performance of an Adele classic.

James Hetfield, the legendary frontman of Metallica, is known for showing a softer side, especially when it comes to his family. Despite Metallica’s global fame for selling out arenas, there was something uniquely touching about a particular performance where Hetfield shared the stage with his daughter, Cali, for a soulful rendition of Adele’s “Crazy For You.”

This father-daughter duo’s heartfelt performance touched both the live audience and the millions of YouTube viewers. Cali’s beautiful vocals were a highlight, and seeing Hetfield strum an acoustic guitar for the slower number added a special touch. Watch the performance below:

This moment between Hetfield and his daughter was even more significant as it took place at “Acoustic-4-A-Cure,” a charity concert co-founded by Hetfield and Sammy Hagar to support UCSF’s Pediatric Cancer Program. The event has drawn big names like Billie Joe Armstrong, Jerry Cantrell, and Pat Monahan.

Metallica is one of the most successful metal bands ever, with a career spanning over four decades, producing metal classics and influencing countless musicians. While they continue creating music today, their iconic albums are cemented in history as genre-defining works. Check out one of their classic performances below:

Metallica’s influence on the global music industry is undeniable, and their list of accolades is impressive for any band, let alone a metal one. Between 1990 and 1992, they won several Grammy Awards, including for ‘Best Metal Performance’ with hits like “One,” “Stone Cold Crazy,” and their self-titled album, Metallica.

Though their lineup has been mostly stable over 40 years, a few key members stand out. Bassist Cliff Burton, who tragically passed away in 1986, contributed significantly to their success, particularly with Ride the Lightning. Dave Mustaine, an early member, left following a dispute and went on to form the legendary thrash band Megadeth.
