The Recording Academy is infusing the Grammy Awards lineup with additional performers to try to live up to the promise that Sunday will be, as billed, "Music's Biggest Night." Kelsea Ballerini, Lukas Graham and Cynthia Erivo, each of whom is nominated for an award this year, will take the stage to perform during the awards ceremony—as will Lady Gaga and Metallica, together.

The news comes just days before the Grammys, scheduled to take place Sunday at Staples Center in Los Angeles and televised on CBS at 8 p.m. Eastern time/5 p.m. Pacific time. The Late Late Show host James Corden will preside.

Ballerini, who is up for the best new artist award, and Graham, who is up for both record of the year and best pop duo/group performance for "7 Years," will be making their Grammy stage debuts. Cynthia Erivo—who won a Tony Award for her portrayal of Celie in The Color Purple and is up for the best musical theater album award—will perform with John Legend in a "tribute to those from the music community we lost this past year." That's a tall order considering the number of music greats who passed away in the last year, including Prince, Leonard Cohen, Sharon Jones, George Michael and more.

Demi Lovato, who is nominated for best pop vocal album, and previous Grammy nominees Andra Day and Tori Kelly will join Little Big Town in a special segment celebrating the Bee Gees and the 40th anniversary of Saturday Night Fever. That performance will presumably be drawn from the "Stayin' Alive: A Grammy Salute to the Music of the Bee Gees" event scheduled to take place two days after the Grammy Awards.

And Lady Gaga—flying high off her highly lauded Super Bowl halftime performance (in which she "flew" from the top of the stadium onto the stage set up on the field)—will perform a duet with Metallica, Rolling Stone reports. Gaga and Metallica are not the only interesting pairing viewers can look forward to: Alicia Keys will perform with Maren Morris; Anderson .Paak will perform with A Tribe Called Quest; and The Weeknd will perform with Daft Punk.

Other artists already scheduled to perform on Sunday include Adele, William Bell, Chance The Rapper, Gary Clark Jr., Bruno Mars, Sturgill Simpson, Carrie Underwood and Keith Urban.
