The lineup for the "Healing in the Heartland: Relief Benefit Concert" now boasts Usher and Darius Rucker.

Organized by The Voice coach and country singer Blake Shelton, the concert will benefit those affected by the devastating tornados that hit Oklahoma and the Midwest least week. Slated for May 29, the concert will air on NBC.

However, on Monday it was announced that another Voice coach would hit the stage with Shelton, according to Deadline. Usher will be on the bill and brings a little bit of hip-hop to a country-dominated lineup.

Darius Rucker was also added to the billing on Monday, according to Deadline. The pop star turned country boy recently released his new album, Treu Believers, and fans might be able to see him perform a few of his new tracks.

Shelton is an Oklahoma native and managed to quickly organize the concert as a way to give back

"Everyone has their way to help, and mine as an entertainer is to perform to help raise money and awareness for this tragedy," Shelton said according to USA Today.

Also performing is Shelton's wife Miranda Lambert, Reba McEntire, Vince Gill, Rascal Flatts, and Ryan Tedder of One Republic. The concert will air at 9 p.m. on NBC.
