If you’ve ever seen Jason Isbell and his wife, Amanda Shires, perform together, you know they are a formidable tandem capable of evoking a range of emotions from their audience. Their new song, “The Color of a Cloudy Day,” does just that—dueling vocals coupled with Jason’s guitar and Amanda’s fiddle create a powerful combination.

Co-penned by Jason and Amanda, “The Color of a Cloudy Day,” was originally recorded for a movie called Fear 13, but was never officially released until today (Sept. 9) via Amazon Acoustics, which is an original playlist that features newly-written and recorded songs from artists and bands such as O.A.R., Train, Rodney Crowell and more.

“The [song’s] protagonist isn’t perfect, but doesn’t deserve to be isolated, and feels he’s being treated like a caged animal,” Jason said to The Wall Street Journal. “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.”
