As previously reported, Oklahoma country music superstar Blake Shelton and his wife Miranda Lambert delivered an emotional tribute to his tornado-ravaged home state to open Tuesday night’s live episode of “The Voice.”

On Sunday and Monday, a series of devastating and deadly tornadoes ripped through central Oklahoma, killing at least 26 people and leveling houses, schools and businesses.

The country music power couple, who live in Tishomingo, performed a heartfelt acoustic rendition of Lambert’s emotional chart-topper “Over You” on Tuesday’s “The Voice.” Check out these NBC photos of the performance.

The couple co-wrote the song about the death of Shelton’s brother, Richie, in a car accident. The song has earned song of the year honors from the Academy of Country Music and Country Music Association.

After Tuesday’s episode of “The Voice,” Shelton announced that he was planning to perform a televised benefit show to aid with the Oklahoma tornado relief efforts.

Shelton’s “Healing in the Heartland” tornado benefit concert is set for Wednesday at Chesapeake Energy Arena, reports the Associated Press.

The event will be televised live on NBC.

The “Healing in the Heartland” lineup and more details will be announced Friday.
