CMA Fest 2019, Day 4: Luke Bryan Shuts It Down, Maren Morris Slays the Stadium [PICTURES]

Luke Bryan closed out CMA Fest 2019 on Sunday night (June 9) with a cover of Bon Jovi's "Livin' on a Prayer," but before those final notes rang out from Nissan Stadium, Maren Morris, Chris Janson, Keith Urban and more helped shut down the annual event.

Although some of the free daytime shows got rained out on Sunday, and the Nissan Stadium shows were delayed due to bad weather, the last day of CMA Fest 2019 still packed plenty of big moments. Morris invited Brandi Carlile up on the big stage to sing their duet "Common," while Trisha Yearwood debuted her brand-new single, "Every Girl in This Town."

In addition to the free daytime performances and nightly Nissan Stadium shows, CMA Fest also includes concerts at Ascend Amphitheater, Fan Fair X and a number of artist-specific fan club parties and events. The stars who perform during the four-day event, which began on Thursday (June 6), donate their time, so all of the proceeds benefit the CMA Foundation, which focuses on assisting music education programs.
