"It’s been three years since we were lucky enough to participate in the awards show when we last performed with world-renowned Chinese concert pianist Lang Lang and we’re thrilled to be asked back," the wrote. "We have something very unique and special planned for this celebratory night, so tune in to watch on CBS-TV."

The show's performance roster also includes Beyonce, Katy Perry, The Weeknd, Daft Punk, Adele, Metallica, Carrie Underwood, Bruno Mars, Keith Urban, Anderson .Paak, A Tribe Called Quest and many others. The Grammy Awards will take place Feb. 12 at the Staples Center in Los Angeles with host James Corden. It will be broadcast live at 8 p.m. EST on CBS.
