Garth and Trisha held a press conference on Thursday, October 28th at Tennessee's State Capitol to make their big announcement.
The benefit concert will support the ongoing flood relief for Nashville. Garth says it's simply his way of trying to help, and Trisha says that they've learned that rebuilding is a slow process after watching what has been happening in New Orleans following Hurricane Katrina five years ago.
Their show will raise money for the Community Foundation of Middle Tennessee, and will be at the Bridgestone Arena in Nashville on December 17th.
This will be Garth's first Nashville concert since 1998!
Tickets are $25 with 100% of the proceeds going to charity.
More details will come out on November 3rd.
