When an all-star arrangement of musicians come together to celebrate the work of one of rock 'n' roll's great originators, someone's definitely gonna have 'em saying "wow." (With or without the 720S bumpin' Fall Out Boy.) Still, you may be surprised to learn of an unexpected alliance forming between one performer and a certain Bonnaroo headliner.

Indeed, Post Malone—the red-hot hitmaker who's sandwiched between sets from Phish this summer in Manchester, Tennessee—will join fellow artists Ed Sheeran, Shawn Mendes, Adam Lambert and John Legend in paying tribute to rock icon Elvis Presley on NBC's upcoming Elvis All-Star Tribute special, which airs Feb. 17 at 9 p.m. EST.

But it's country star Keith Urban who'll go one-on-one with Posty during the small-screen homage. The singer specifically tabbed Malone for a collaborative performance of Presley's "Baby What You Want Me To Do," according to Variety.

And all of it will serve to evoke the sound and feel of Presley's original "'68 Comeback Special," which also aired on NBC. As a further nod, the tribute is being broadcast the day the "King of Rock and Roll" would have turned 84.

Below, watch some of Elvis' 1968 special.

• “Trouble”/”Guitar Man” - Blake Shelton
