The song also features additional vocals by Jenny Lewis, as well as saxophone from Kamasi Washington and drum programming by Kendrick Lamar producer Sounwave.
St. Vincent first worked with Sounwave on a cover of the Stones' "Emotional Rescue
" for the movie A Bigger Splash
. She recalled to Pitchfork
"We hit it off and worked on a couple of other tracks together. When Kendrick was making DAMN
., Sounwave came to my studio, and I just freestyled on guitar for a long time on different ideas that Kendrick was working on. None of that stuff ended up getting used on the record, but Sounwave is always looking for the next, the most innovative thing."
