We got to the root of the mysterious Instagram images posted by Jason Aldean, Luke Bryan and Kelsea Ballerini. All three artists posted individual photos on Instagram—without captions—that depict their likenesses created on landscapes.

The crop circle designs were created by Nashville artist Stan Herd in celebration of Spotify’s Hot Country playlist, which gives its 4.8 million followers access to songs and original video content. Stan recreated the faces of the country stars and the Spotify Hot Country logo in fields outside Lawrence, Kansas. Each crop circle took approximately one week to create and will last for approximately three weeks.

“I usually begin with a simple concept that speaks to something I believe in and a statement that I think is important to make with my art,” said Stan. “When I get to the point that I decide to actually take the drawing to a field, I create a gridded drawing to the site and try to gauge how it might fit the field or terrain. I work with crews to lay out the grid, maybe one inch equaling 20 feet, and begin the simple outline with a weed-eater or other tools into existing crops or vegetation. Then we begin to gauge the work through aerial recon or drone shots.”

“This year Spotify is making a concentrated effort to shine a spotlight on country music and to find truly unexpected ways to celebrate all things country,” said Brittany Schaffer, head of artist and label marketing at Spotify. “To give our fans something special we decided to work with artist Stan Herd to bring to life three of the world’s biggest country artists on a beautiful Kansas landscape to pay homage to the Heartland and country music today.”
