When Lady Gaga and Metallica Rocked the Grammy Stage Together

One of the most unexpected and unforgettable Grammy moments took place on February 12, 2017, when Lady Gaga joined Metallica on stage for a fiery duet of “Moth Into Flame” at the 59th Annual Grammy Awards in Los Angeles.

🎸 It All Started at a Dinner Party

This unlikely collaboration began at a dinner hosted by Bradley Cooper, where Metallica drummer Lars Ulrich and Gaga were seated together. Ulrich recalled:

“We were sitting next to each other, and I said, ‘We’re doing the Grammys in a couple of months—want to join us?’ She said, ‘Yeah, that would be great!’”

The rest is rock history.

🎤 The Performance That Broke Barriers

Despite a brief microphone glitch during the live show, Gaga and James Hetfield delivered a high-energy performance that thrilled fans and proved pop and metal can share the same stage.

The rehearsal footage, now available online, shows the duo’s natural chemistry and passion without the pressure of a live crowd.

It’s a rare behind-the-scenes look at how a Grammy moment is made.
