Husband-and-wife Jason Isbell and Amanda Shires have paired up for a tender new duet called “The Color Of A Cloudy Day.” According to WSJ, they originally wrote the song for a movie soundtrack but it never saw the light of day, so they re-recorded it for Amazon’s Amazon Acoustics playlist. “The protagonist isn’t perfect, but doesn’t deserve to be isolated, and feels he’s being treated like a caged animal,” Isbell explained to WSJ. “I think all couples deal with these feelings on some level at certain points in a relationship, but Amanda and I spend a lot of time apart because of our work, so we can certainly relate.”

Shires added: “I remember it beginning in the living room. Jason was playing the guitar like he always does there. Then, he moved to the kitchen with the bones of it, and a start at the melody. I was washing dishes and he started talking to me about the character and the situation of the song. I came at it thinking about what I hoped the character would say to me in a letter if I were in that situation.”
