The Jonas Brothers are just not stopping from taking over the world.

The musical trio — Nick, Kevin and Joe — are set to release their fourth album, titled, Lines, Vines and Trying Times, on June 15th.

Nick tells Billboard.com of the songs on the CD: “This album is taking steps. We’re trying to learn as much as we can, continuing to grow. [The album is] our journal in songs [about] all things we’ve gone through, personal experiences we get inspiration from. We’ve also been working on trying to use metaphors…to kind of mask a literal thing that happens to us.”

The JoBros just recently added two more dates to their world tour:
– July 11 Allstate Arena Chicago, Ill.
– August 9 Staples Center Los Angeles, CA
