Gwen Stefani's bandmates Tony Kanal, Tom Dumont, and Adrian Young formed the group with AFI frontman Davey Havok in 2014 and now their 1980s new wave-influenced sound is ready for fans.

"It's like a rebirth, a really beautiful, pure and positive thing," Kanal tells Rolling Stone.

The band's first track, Kill for Candy, was released on Thursday (02Mar17), and the group's debut album will come out in May (17).

Talking about the beginning of the band, Kanal says, "Tom, Adrian and myself have realised after all these years that we really love playing music together, and we'd been flirting for a long time with the idea of doing another project. We finally started writing some music together.

"We knew Davey from the music scene, and seeing his bands play. Back in 2012, his band Blaqk Audio supported No Doubt when we played some shows... and he was incredible; he's an incredible frontman, one of the best. And then he moved to L.A. about a year later, and I would see him out and about, since we eat at similar places.

"It was like all these little seeds were planted along the way to finally make us go, 'Wait a minute, let's ask Davey!'"

The No Doubt trio and Havok kept their band plans a secret for 18 months, telling only their "significant others".

"We didn't know what it was going to become," Kanal adds. "It's almost like you don't want to talk about it - you just want to do it, and see if something is going to come of it."

And the rocker insists there are no plans to disband No Doubt now that Dreamcar have released their first single.

"Right now Gwen's focusing on her solo stuff, and we're focusing on Dreamcar," Kanal adds. "No Doubt will always be there; we've experienced things together that no one else will ever experience with us. It's a family that will always be there, and the music we've created will always be there. We're just going through a period where everybody's kind of doing their thing."
