The group have brought in Nigel Godrich (Radiohead, Beck) to handle mixing duties for their 11th album after teaming up with producer Danger Mouse on the recording. "Started mixing the new record today!," tweeted Smith. "@nigelgod at the helm."

Frontman Anthony Kiedis praised Danger Mouse's work on the project last October in an interview with Rolling Stone, saying, "He's very good about coming up with super-modern ideas, but he'll also touch on the acoustic guitar in the control room and strip the song down to its acoustic essentials. Which is a beautiful place to be."
