Miranda Lambert announced a free, surprise show at a small bar in Nashville on Tuesday night.

Lambert announced the show just hours before it began on Instagram at Exit/In on Tuesday night.  The show was without a fancy set, lights or videos.  It was simply a chance for the singer and her band to run through her show in front of a few hundred fans!

According to Yahoo,

"While the performance featured Lambert's biggest hits, including "White Liar," "Mama's Broken Heart," "Automatic" and her new single, "Little Red Wagon," she also threw in a few covers. RaeLynn and Gwen Sebastian joined Lambert for a trio performance of The Dixie Chicks' "Cowboy Take Me Away," and she and Sebastian closed the show with a duet on "Girl Crush" by Little Big Town, which she has said is her favorite band."

What a cool experience!  I actually saw the Instagram post last night while I was sitting at the airport....  I was jealous that I was stuck in Atlanta and not stuck in Nashville!
