It's been more than three years since Maroon 5's last album, but fans won't have to wait much longer to hear the group's new music. The quintet kicks off a national tour July 30 in support of its newest release, 'Hands All Over,' which hits stores Sept. 21.

PopEater caught up with the band during tour rehearsals in Los Angeles, where they previewed tracks from 'Hands All Over' and discussed the writing process for their new album. "The lyrics are very emotional on this record," keyboardist Jesse Carmichael said, "and I think the lyrics stepped up -- more than anything on this record -- to be very mature."

For this album, the band worked with producer Mutt Lange, who has produced albums for artists such as AC/DC and the Cars. "The whole process of writing this album was we push ourselves or be pushed by Mutt as hard as necessary," frontman Adam Levine said. "We've never really worked with anybody who challenged us like that." Check out the exclusive footage from PopEater's interview below.
