The Grammys just announced more acts set to perform at their 57th Annual Awards telecast. It's gonna be a good (and strange) one.
Beck will be joined by Coldplay's Chris Martin. Sia will perform unaccompanied.
Three-time Grammy winner Beck is nominated for four awards: Album Of The Year and Best Rock Album for Morning Phase; and Best Rock Performance and Best Rock Song for "Blue Moon."
Seven-time Grammy winner Chris Martin holds three nominations with Coldplay: Best Pop Duo/Group Performance for "A Sky Full Of Stars," Best Pop Vocal Album for Ghost Stories, and Best Music Film for Ghost Stories.
This will be the first performance on the Grammy stage for Australian singer/songwriter Sia, who is up for Record Of The Year, Song Of The Year, Best Pop Solo Performance, and Best Music Video for "Chandelier."
Mary J. Blige will take the stage with Sam Smith.
Also announced: Country singer Brandy Clark will be performing with two-time Grammy winner Dwight Yoakam.
Herbie Hancock, John Mayer, and Questlove will join Ed Sheeran for what will be, presumably, the night's most diverse performance.
Oh, wait. Never mind. Internationally acclaimed pianist Lang Lang will join Jeff Lynne's ELO and ... Ed Sheeran (again) for a performance. And two time Grammy winner (and 20 time Latin Grammy winner) Juanes will also play live on Sunday's big show.
Previously announced performers include [DEEP BREATH] AC/DC, Tony Bennett with Lady Gaga, Eric Church, Common with John Legend, Ariana Grande, Hozier with Annie Lennox, Jessie J with Tom Jones; Miranda Lambert, Adam Levine with Gwen Stefani, Madonna, Rihanna with Paul McCartney and Kanye West, Ed Sheeran (again!?), Sam Smith (also again), Usher, and Pharrell Williams.
