Katy Perry, Lorde, Robin Thicke and Metallica will take the stage at this year's Grammy Awards, Billboard reports, joining an already stacked lineup that also includes Daft Punk, Pink, Kendrick Lamar, Merle Haggard and more.
Lorde will make her Grammy telecast debut after notching four nominations – including Record and Song of the year for "Royals" – and performing at the nominations ceremony back in December. Perry also performed at the Grammys Nomination Concert Live!! event, via a satellite feed from Canada, and will vie for Song of the Year too with "Roar" off her fourth album, Prism (the track will also compete for Best Pop Solo Performance).
Metallica's performance will mark the group's first at the Grammy's since 1991, and to honor the occasion the metal heroes will take the stage with master pianist, Lang Lang, who is also the Grammy Cultural Ambassador to China. Thicke, who is up for three Grammys, will take the stage with jazz-rockers Chicago.
The Grammys already have a handful of unique collaborations lined up for this year, chief among them what's sure to be an epic performance from Daft Punk, Stevie Wonder, Nile Rodgers and Pharrell Williams (the latter two appeared on the Robots' summer smash "Get Lucky," which is up for Record of the Year and Best Pop Duo/Group Performance).
Other previously announced performances include Pink and fun. frontman Nate Ruess (their duet "Just Give Me A Reason" is up for Song of the Year and Best Pop Duo/Group Performance), Kendrick Lamar and Imagine Dragons, and, to cap it off, Merle Haggard, Kris Kristofferson, Willie Nelson and Blake Shelton.
The 56th Annual Grammy Awards will air live from Los Angeles January 26th on CBS, with LL Cool J returning as host.
