In October, a bevy of musical talents gathered to honor the King of Rock 'n' Roll for the 50th anniversary of his '68 Comeback Special. On Feb. 17, those performances — dubbed Elvis All-Star Tribute — will air on NBC, but fans can get a sneak peek now. Flip through the photo gallery below to see Blake Shelton, Carrie Underwood, Little Big Town and more at the big event.

Hosted by Shelton (who will also perform multiple times during the two-hour show), the Elvis All-Star Tribute will also feature Kelsea Ballerini, Dierks Bentley, Pistol Annies, Darius Rucker and Keith Urban. Urban teased back in November that he worked with rapper Post Malone for the event.

"He's the real deal," Urban says of Malone. "He's so eclectic. So steeped in all kinds of music. I love him."

Elvis All-Star Tribute is scheduled to air on NBC beginning at 9PM ET. In addition to the musical performances — which will also come from John Fogerty, Jennifer Lopez and more — the show will feature interviews with Presley's wife Priscilla, '68 Comeback Special director Steve Binder and Presley's daughter, Lisa Marie Presley.
