Robert Earl Keen's flood relief concert in New Braunfels will feature performances from Miranda Lambert, Ray Wylie Hubbard and more.

Buc-ee's and Keen on Wednesday announced the "Applause for the Cause" fundraiser concert, Aug. 28, at Whitewater Amphitheater in New Braunfels.

Just as we have seen with other natural disasters, the country music world stepped up in a big way, and fast. Right after the floods, Texas legend Robert Earl Keen took to social media with a heavy heart to share his thoughts and announced that he was planning a benefit show to help his home state.

The country singer's brother and sister-in-law passed away and their children are missing after the devastating floods that hit Texas on July 4.

Gary, DeeAnn, Jake and Megan all lost their lives. Harley is still among the missing. Both families lived in Canyon Lake but have ties to the Houston and Mont Belvieu areas. Hutch and Beth Bryan, formerly of Houston, died in the Texas Hill Country flooding.

For the third straight day, thunderstorms have posed what meteorologists call life-threatening conditions in the Hill Country, where flooding earlier this month killed at least 131 people.

More than 130 people are dead after devastating flooding in the Texas Hill Country that began early on the Fourth of July.
