Miranda Lambert, Reba McEntire, Vince Gill, and others are signed to perform at the concert, which will be simulcast, or run on a delayed basis, by other networks of NBC Universal, including Style, G4, Bravo, and E!, as well as Viacom-owned CMT.

According to NBC, the event will raise funds for the United Way of Central Oklahoma May Tornadoes Relief Fund, which will use funds for immediate, intermediate and long-term recovery and rebuilding in the wake of the tornadoes that hit Moore, Okla. this week.

Shelton, who currently lives in Tishomingo, Okla., and McEntire also hosted the "Tornado Relief Concerts" for victims affected by the Atoka County tornadoes, in 2011. The two-sold out concerts raised $500,000 for those victims.
