Sounwave explained the pair's process, saying that they're always in creative mode.
"It's just the ideas never stopped," Sounwave explained. "That's one of the main reasons I go on tour with him, is to create the next album. We can't skip a beat. We have to just keep going. There are no breaks."
To his point, following the release of 2014's To Pimp A Butterfly, Kendrick quickly dropped Untitled Unmastered, a string of songs that were made during the same period as the critically-acclaimed album. In a new interview with GQ, the producer also explained that making Kendrick's most recent project was arduous at times, admitting that he knew it was going to be a "tough listen."
"This was the toughest and longest creative process for me," he admitted. "We didn’t necessarily have everyone come to us; we traveled. The first portion of the album—or the first brainstorming of the album—happened in London. We just took a couple of us—I think it was me, DJ Dahi, Baby Keem, Bekon—and we just created for a week in London, just to get out of our element and try something new. And in that session, I think, this is probably early 2019, only one song made it. But at that moment, we felt we had the full album, the core of the album done."
Kendrick kicked off the North American leg of his Big Steppers Tour earlier this month and will wrap it up in L.A. this September.
