It's not as if the Indigo Girls haven't stayed busy since their last album with various tours, solo projects, restaurants and a dozen other things.

But Amy Ray and Emily Saliers are returning to the form that always makes their longtime fans the happiest and releasing their first new Indigo Girls album in four years.

“One Lost Day” will arrive June 2. It’s described as a “landscape of truly original sounds and stories ranging from stark intimacy to bombastic pop and grind.”

The 13-track album was produced by Jordan Brooke Hamlin (Lucy Wainwright Roche) and recorded in Nashville. Some of the mixing took place at Atlanta’s Parhelion Recording Studios. Musicians Brady Blade and Carol Isaacs, heard on the Girls' “Beauty Queen Sister” album returned, along with their touring band.

Ray and Saliers will hit the road next month and have a date plugged in for June 26 at Chastain Park Amphitheatre. Series tickets are on sale now, and individual show tickets will be available starting March 28.
