Sonnymoon's Anna Wise (who sang on Lamar's good kid, m.A.A.d city
") also contributes vocals, putting a female touch on the cut. She contributed to several other To Pimp A Butterfly
tracks. Wise told Billboard
magazine in March 2015: "I just kept going back and forth with him. He would fly me out and I would stay for extended periods of time. Even up to about a month after GKMC came out, I was kind of jumping around, I wasn't really staying in Boston at that time. I was upstate [New York], I was in San Francisco. Sonnymoon did three tours -- so we had a lot of stuff going on. But in between that, I would always come back to him."
"We immediately started working on it," she added, "we did the "Institutionalized" intro almost two years ago."
