In December 2019 Nettles ended her solo deal with Big Machine Records but her duo Sugarland signed an exclusive deal with Big Machine.

To coincide with the sixteenth anniversary of the 9/11 attack, Nettles released a song called "King of the City", which tells the story of an immigrant who lost his life during the tragedy. Of the track, Nettles said "it has been so long since I started writing this song, but I was only able to finish it in the last year. I was inspired by the political tensions in our country right now. I want to humanize the immigrant story as an American story, and allow people a different narrative from what they might, or might not, be seeing on the news or in their communities".
