Lambert, Ingram and Randall performed their song "Two-Step Down to Texas" during Monday's episode of the NBC late-night show.
The trio of country music artists performed together while seated on stage. Lambert wore a blue and red floral-print shirt with a matching red cowboy hat.
"Two-Step Down to Texas" appears on Lambert, Ingram and Randall's album, The Marfa Tapes. The trio released the album in May.
The Marfa Tapes features the singles "In His Arms," "Tin Man" and "Am I Right or Amarillo." Lambert, Ingram and Randall recorded the "raw" new album in Marfa, Texas.
"You can hear the wind blowing, the cows mooing... We wanted you to feel like you were right there with us, sitting around the campfire, escaping the world, disappearing into the music," Lambert said on Instagram in March.
"Every time I need an escape, I go to Marfa, TX. @JackIngram, and @jonrandallmusic come. We recharge. We get inspired by its beauty. We write songs," she added.
