Before she announced her upcoming Postcards From Texas album, Miranda Lambert teased the project by sending out physical postcards with song titles written on them.

Now, the singer’s continuing to find a unique way to connect with fans ahead of the album’s release. This time, though, she’s going digital.

On Sunday (Aug. 4), a Lambert fan received a special update from the singer’s text line, and she turned to social media to share her excitement. The fan posted a screenshot of a text Lambert sent out to her fan club members, which includes an audio file of an unreleased song called “No Man’s Land.”

“Stopped everything I’m doing bc I just received this text from [Miranda Lambert] and I NEED TO LISTEN,” she wrote.

Lambert shared the post, writing “A Sunday song surprise,” and sharing the number to join her text chat and listen.

“No Man’s Land” comes in at No. 10 on the track list of Postcards From Texas, which also includes already-released songs like “Dammit Randy” and “Alimony.” According to the audio clip Lambert shared with her fans, the new song is a mid-tempo ballad about loving — and letting go of — a woman with a wild heart.

“So love her like a Mustang / Like a wild thing / Better let her run free,” Lambert sings in the clip. “If she wants to love ya / You let her love ya / You give her everything …”

Postcards From Texas is due out on Sept. 13. Lambert has said the project has deep roots in her home state, and its only duet is with fellow Texan Parker McCollum.
