You may have seen some of the mysterious videos that many country artists such as Carrie Underwood, Brett Eldredge, Little Big Town, Keith Urban and Dierks Bentley have posted on their social media sites. The videos show a short clip of the artist singing a snippet of a song, ending with the date 9.20.16 and #Forever Country on a black background. Strange, right?

Well, we now know that in honor of the 50th annual CMA Awards on Nov. 2, the CMA has created a major event to celebrate its golden anniversary: 30 country artists singing one song. Those clips represent the single “Forever Country,” which will be performed by 30 of country’s biggest CMA-award-winning artists and accompanied by a music video.

Produced by songwriter Shane McAnally and directed by Joseph Kahn, the video is set to a medley of John Denver’s “Take Me Home, Country Roads,” Willie Nelson’s “On The Road Again” and Dolly Parton’s “I Will Always Love You.”

You will be able to hear the song “Forever Country” tomorrow (Friday, Sept. 16) when the CMA teams up with country radio to have hundreds of stations simultaneously premiere the song at 8:30 a.m ET. But alas, to build the suspense, you must wait until Tuesday, Sept. 20—hence the date on the video clips—to see the worldwide premiere of the video.

“‘Forever Country’ is a moving tribute to country music, country music fans, and the artists who have built this format into what it is today,” said Sarah Trahern, CMA CEO. “This music video is the product of the CMA Board of Directors who came together in support of this project as a celebration of the 50th anniversary of the CMA Awards, a statement on the heritage and future of the country music industry, and a reflection of this year’s Awards theme: Then. Now. Forever Country.”

For now, take a look at the clips from CMA Award winning artists and get ready for Sept. 20.
