30 Seconds To Mars have finished their new album.

Singer Jared Leto confirmed the "Beautiful Lie" rockers - also including Shannon Leto and Tomo Milicevic - are putting the finishing touches to their fourth album, but the recording is complete.

"This is the first time I'm really talking about the album, and when you talk about these things it helps you put them into perspective. I just mastered it two days ago, and we're still toying with it, but it's been turned in and it's finished. I wrote and recorded about 70 songs for this album, and I think there's a feeling that all of us in the band have that, especially after touring as long as we did last time, that this is a really important album for us; it's a critical album for us. It's an evolution, this album is more of who we are than we have ever been before, and we've gone to an entirely new place, which is incredibly exciting. And it's provocative at the same time, because changes bring new opportunities, new challenges, a chance to learn."

Jared added while the release date for the album has yet to be decided, the group have shot a music video for their next single. "So much of the stuff is [to be confirmed], but we've shot a video, we've launched a single, we've finished an album, we have the most incredible things to share with our fans. It's brand-new territory for us, both musically and creatively," he said.
