Earlier this week, Metallica announced that they had to postpone their upcoming performance in Denmark due to singer James Hettfield‘s illness, which affects his throat. This news brought questions regarding their performance at The Grammys on Sunday night. However, just in case Hettfield isn’t back to 100%, they’ve recruited some help for their vocal duties–recent Super Bowl LI Halftime Show star Lady Gaga 

While Metallica and Lady Gaga sound like a strange pairing, the choice makes more sense than you may think. Some of Gaga’s earliest singing gigs were with a Led Zeppelin tribute band (when she still went by her given name, Stefani Germanotta). Gaga recently got the Led out on Howard Stern, impressively howling a few lines from “Black Dog” and speaking about how to train your voice to withstand the wear of such vocal parts. If her searing wail in the video below is any indication, Lady Gaga will fit right in with Metallica for the televised performance.

You can catch Metallica with Lady Gaga, as well as a slew of other star-studded collaborations (like Daft Punk with The Weeknd and A Tribe Called Quest with Anderson .Paak) on Sunday night at 8pm Eastern on CBS.
