Jared Leto says his band’s new album is a “complete transformation” for them.
The actor is frontman of American rock band 30 Seconds to Mars, which also consists of Shannon Leto and Tomo Milicevic.
The group have recorded new music in Asia, Europe and America for the album which is due for release next year.
"It's stronger, better and more evolved. It's a complete transformation for us,” Jared revealed to the BBC.
“[We have] cut out a lot of fat and focused on the core of what we do.”
Prior to the recording of their fourth musical offering, there had been rumours 30 Seconds to Mars would split.
Their last album This Is War came out in 2009 and Jared says the temporary break was good for the band.
"People started to ask us about a new album. We had been on the road for almost two and a half years and I didn't know. I had no idea what the future held. I don't think any of us knew. We told the truth,” he confessed.
"There were a lot of questions we had. There was a certain amount of fragility when we thought about what we were doing with our lives at that moment. It wasn't a bad thing. It's good to question and debate with yourself."
The 40-year-old artist says he and the group are now back and better than ever.
"I really think that this could be the best thing that we've ever done,” he added.
