This time around, Rhiannon Giddens of the Carolina Chocolate Drops, sings the lead vocal on "Spanish Mary," which she also co-wrote. "Out of all the lyrics I looked through for the New Basement Tapes project, the one for 'Spanish Mary' attracted me first - here was a ballad, and I know ballads," Giddens said of the track in a press release.

"It's also set in the Caribbean, so I felt the deep African sound of the minstrel style banjo (circa 1856) was appropriate. It was an absolute thrill to get to set music to Dylan's lyrics, what an opportunity."

The other members of the group playing on the track include Elvis Costello, Taylor Goldsmith of Dawes, and Marcus Mumford of Mumford & Sons, along with producer T Bone Burnett.
