Earlier today (22 March) the official trailer for the film adaptation of Delia Owens' novel Where The Crawdads Sing was released, and it features a preview of a new Taylor Swift song titled "Carolina" that she contributed to the film.

Swift revealed in an Instagram post that she reunited with Folklore and Evermore collaborator Aaron Dessner to produce the new song. "Where The Crawdads Sing is a book I got absolutely lost in when I read it years ago," Swift wrote. "As soon as I heard there was a film in the works starring the incredible Daisy Edgar-Jones and produced by the brilliant Reese Witherspoon, I knew I wanted to be a part of it from the musical side. I wrote the song "Carolina" alone and asked my friend Aaron Dessner to produce it. I wanted to create something haunting and ethereal to match this mesmerizing story. You’ll hear it fully soon, but for now check out the trailer for a clip!"

Where The Crawdads Sing will star Daisy Edgar-Jones (Normal People), Harris Dickinson, David Strathairn, Garret Dillahunt, Taylor John Smith and more, and is directed by Olivia Newman.

Taylor Swift is yet to share a release date for "Carolina".
