Kerrville native Robert Earl Keen is circling the wagons to support Hill Country flood relief. After the July 4 storms, the Texas country legend quickly got to work on an all-star benefit concert on August 28 at New Braunfels Whitewater Amphitheater, enlisting Buc-ee's, Tyler Childers, Miranda Lambert, Jack Ingram, and more to lend a boot.

More than just a concert, Buc-ee's Presents Robert Earl Keen and Friends: Applause for the Cause will be a mini music festival with performances starting at 3 pm. All of the proceeds will benefit the Community Foundation of the Hill Country's Kerr County Flood Relief Fund.

"This is a star-studded lineup with music starting in the mid-afternoon and lasting far into the night," says Keen via a release. "We must help everyone as much as we can, for as long as we can."

Arch "Beaver" Aplin III, the founder of Buc-ee's, swiftly got involved in the project. The convenience store giant has already pledged $1 million to flood recovery and cleanup efforts.

"We are pleased to have the opportunity to support the relief efforts of so many for our beloved Hill Country. The tragedies are beyond belief," says Aplin in a statement. "Buc-ee's teaming with Robert Earl Keen and friends for this benefit concert just seemed like the right thing to do. When we learned 100 percent of our commitment goes to the Community Foundation of the Hill Country, we were all in."
