Miranda Lambert attended U2’s Joshua Tree Tour in Louisville, Ky., in June and was so moved by the experience that she’s been working a cover of “I Still Haven’t Found What I’m Looking For” into her recent sets.

“The only way to stay inspired and to find how to become a better performer is to gather from inspirational people,” said Miranda to Kix Brooks, host of American Country Countdown. I just want to be a sponge because some days I feel like I’m just getting started and some days I feel like I’ve been doing this for 30 years [laughs], you know? So, I’m trying to find a balance and keep that balance of inspiration and growing and learning.”

At the Faster Horses Festival in Brooklyn, Mich., in July, Miranda closed her headlining performance with a rendition of “I Still Haven’t Found What I’m Looking For,” featuring additional vocals from Gwen Sebastian and Blu Sanders.
