Joe Jonas’ upcoming album is not technically his solo debut: Back in 2011 during a Jonas Brothers hiatus, the middle JoBro released Fastlife, a club-aimed rhythmic pop foray featuring contributions from Lil Wayne and Chris Brown that couldn’t quite turn the then-22-year-old into a radio star. “I have so much love for those songs — they actually aged pretty well!” Jonas says today with a wide smile. “But it feels like a different person.”

Fastlife might as well be a lifetime ago for Jonas, now 35. Since then, he found his radio hit with 2015’s “Cake by the Ocean” as the leader of pop collective DNCE, then reunited with his siblings Nick and Kevin in 2019, for a Jonas Brothers comeback that produced the No. 1 smash “Sucker” and a global arena tour, among other achievements.

Jonas also married actress Sophie Turner in 2019, welcomed two daughters, then experienced a very public divorce in 2023. “I was going through a lot of life changes,” he says of the past few years, “finding out who I was as a person and father and friend, and living under the microscope of what the music industry can be. And I think, at such a crazy time in my life, I looked to music as an outlet.”

The result is Music for People Who Believe in Love, a solo album full of unvarnished thoughts and sonic experiments that Republic Records will release Oct. 18. The full-length doesn’t sound anything like Fastlife, but it doesn’t resemble Jonas Brothers or DNCE, either. Jonas lands on a shimmery pop sound that synthesizes a wide array of influences, from garage-rock to alt-pop to ’90s country, while singing about navigating life’s uncertainties and finding gratitude amid loss.

“Things you can’t imagine/Remind you of what you’ve always had/Maybe they need to happen/So you know the worst ain’t all that bad,” he sings on “My Own Best Friend,” a pleading anthem marked by mournful whistling. Elsewhere, Jonas races through a fuzz-heavy synth workout on “Velvet Sunshine,” offers a gently strummed “lullaby to my kids” on “Hey Beautiful” and, on the wide-reaching lead single, “Work It Out,” addresses his “head full of insecurities” while slipping into falsetto over a percolating beat.

Jonas says that Music for People Who Believe in Love began with the song “Only Love,” a funked-up and flirtatious pop-rock jam that he originally conceived with his brothers. During the writing process in Australia as they worked with producer Joel Little, “I noticed that the song was going toward the direction of some personal stuff that I went through,” Jonas recalls. “So I go to Kevin and Nick, ‘Hey, can I use this as a catapult to go explore what this sound could be, and also what I’m trying to figure out emotionally?’ They were very supportive — Nick said, ‘Well, damn, I really like that song. But I get what you need to do, so go for it.’ ”

Jonas quickly went to work, corralling studio whizzes including Alexander 23, Justin Tranter, Jason Evigan and Tommy English to Los Angeles’ House of Blues studio and knocking out the majority of the album in two-and-a-half weeks. Following the sunny Jonas Brothers full-length The Album in spring 2023 — and then a slew of tabloid headlines detailing his divorce last fall — Jonas says that hunkering down on a more personal project ultimately proved to be therapeutic.

“It was scary at times, and also freeing,” he says. “I’m not trying to come for anyone on this album. I’m not trying to put stuff on blast. I have a beautiful life that I’m grateful for. I’ve got two beautiful kids. I’m a happy person, and the music needed to resemble that — but also, the journey to get here.”

Republic vp of marketing strategy Alyssa LoPresti adds, “This campaign starts and ends with Joe. From his personal taste in music, which is highlighted by [his] notable and exciting choice of collaborators, to the way he’s engaging with fans on his platforms and the content he’s filmed to support the release, it is all authentic to who Joe is and reflective of this chapter of his life.”

Jonas says that more album tracks, and their featured guests, will be unveiled in the coming weeks following the July release of “Work It Out,” and that he’s “definitely” planning to showcase the album live, potentially around release week.

If Jonas’ last solo project was a bid for stardom when he was still figuring out who he was, Music for People Who Believe in Love represents a check-in from an artist at peace with his choices. “At the core of it,” he says, “if this body of work helps people through what they’re going through, that’s all I can really wish for.”
