Lady Gaga & Metallica Come Together for Thrilling Joint Performance at 2017 GRAMMYs: Watch

The GRAMMYs 2017 performance of Lady Gaga and Metallica sounded too wild to believe, but the collaboration actually was one of the most thrilling performances of the night...with only a slight technical glitch.

The pop star and metal outfit came together to sing "Moth Into Flame," a cut off Metallica's 2016 album Hardwired... to Self-Destruct, with Gaga seeming right at home as she donned a cut-up Metallica T-shirt. Sadly, Metallica singer James Hetfield's microphone was not working properly at first but luckily Hetfield joined his pop star collaborator at her mic before his fixed itself.
