They haven't even officially released their first single, but Miranda Lambert's new band, Pistol Annies, are already in high-demand for more music! The all-female trio, comprised of Miranda and fellow songwriters Ashley Monroe and Angaleena Presley, debuted a new tune, 'Better Days,' in front of Miranda's hometown crowd during her Cause for the Paws event. (Watch a fan's video of the performance below.)

On writing 'Better Days,' Angaleena quips, "I thought of the idea for this song when I was literally laying under my car on the side of the road ... tying up my muffler with a guitar string. True story!"

The trio debuted their first single, 'Hell on Heels,' during the ACM Girls' Night Out concert special in April. It's expected to be officially released to radio later this month, with their full-length album due later this year.

"I figured if I get tired of singing by myself, I might as well have some hot women up here on stage with me!" Miranda explains.

Fans can "like" Pistol Annies on their official Facebook page to get up-to-date information on the dynamic new trio.
