When Lang Lang joined forces with Herbie Hancock at the Grammy Awards in 2008, there may have been a few raised eyebrows, but it was not really much of a stretch: Mr. Hancock’s musical language is jazz and Mr. Lang’s is classical, but both are virtuoso pianists who easily found common ground in an arrangement of Gershwin’s “Rhapsody in Blue.”

But though Mr. Lang’s arsenal includes speed and loudness, his newest collaborators, the heavy metal band Metallica, may outmatch him. In what promises to be either an inspired pairing or a train wreck in the making, Mr. Lang will perform with Metallica at the 56th Grammy Awards ceremony on Jan. 26, the National Academy of Recording Arts and Sciences announced on Tuesday. The performance will be Mr. Lang’s first at the Grammys since his appearance since with Mr. Hancock, and Metallica’s first since 1991.

The awards show, which will be broadcast live by CBS, with LL Cool J as the host, will also include several other collaborations. Stevie Wonder and Nile Rodgers will join Pharrell Williams and Daft Punk (who share two nominations for “Get Lucky”); and Robin Thicke will share the stage with the jazz-rock band Chicago. They join several pairings announced last month, including Imagine Dragons and Kendrick Lamar; and Pink with Nate Ruess, of Fun.

Other performers announced on Tuesday include Lorde and Katy Perry, who are each nominated for several awards, including song of the year and best pop solo performance (Lorde for “Royals,” Ms. Perry for “Roar”), and the country music singers Merle Haggard, Kris Kristofferson, Willie Nelson and current nominee Blake Shelton.
