On Aug, 5, Keith Urban shared a photo via social media of the track list for his upcoming 11th studio album, The Speed of Now: Part I, which drops on Sept. 18.

The photo depicted the titles of the album’s 16 tracks, but redacted the names of the two artists featured on Track 1, “Out of the Cage,” as well the artist collaborating on Track 2, “One Too Many,” which was billed as a duet.

On Aug. 17, Keith revealed the names of his mystery collaborators.

“Out of the Cage” features Breland and guitarist Nile Rodgers, while “One Too Many” is a duet with pop star Pink.

“When I collaborate, I’m always looking for that ‘third thing,’” says Keith. “There’s what I do, there’s what my collaborator does, and then there’s this ‘third thing’ that I’m most curious about. That’s what interests me the most—when the sum of the parts becomes even more than what I envisioned. That’s what I love so much about it—finding common ground, shaping it and bringing it together.”

Keith’s upcoming album also includes his 2019 single, “We Were,” which features vocals from one of the tune’s songwriters, Eric Church.

The Speed of Now: Part I will follow Keith’s 2018 album, Graffiti U, which debuted at No. 1 on Billboard’s Top Country Albums chart.
