It's been four years since the Indigo Girls released a new studio album. But now they return with their much-anticipated release 'One Lost Day,' available on IG Recordings/Vanguard Records. With the help of visionary new producer Jordan Brooke Hamlin (Lucy Wainwright Roche) and mixer Brian Joseph (Bon Iver, PHOX, Kathleen Edwards), Amy Ray and Emily Sailers have created a landscape of truly original sounds and stories ranging from stark intimacy to bombastic pop and grind.

On 'One Lost Day,' musicality, whimsy, rawness, sadness and joy move through each of the 13 tracks. This theme is especially evident on the first single, "Happy in the Sorrow Key," written by Amy Ray.

"I drew from lyrics I wrote during some of my travels with the IG's," Amy said. "I was thinking about the things that keep us weighed down with non-acceptance and a refusal to embrace impermanence and suffering. I don't think you can make change for the good until you do, so it's an activist part of me searching for a way to face reality and still have the energy and passion to work for good."

'One Lost Day' was recorded in studios in Nashville, TN and mixed at Justin Vernon's April Base Studios in Fall Creek, WI and at the Parhelion Recording Studios in Atlanta, GA. Musicians Brady Blade and Carol Isaacs from the Indigo Girls' Beauty Queen Sister returned, along with the Indigo Girls' touring band.

Additionally, Amy and Emily brought in Lex Price (k.d. lang, Mindy Smith), Butterfly Boucher (Ingrid Michaelson, Katie Herzig, Mat Kearney), Fred Eltringham (Sheryl Crow, The Wallflowers, Gigolo Aunts) and Chris Donohue (Dave Matthews, Patty Griffin, Lucinda Williams, Robert Plant) to bring a good dose of infectious energy and creativity to the scene.
