|Jonas BrothersFor Jonas Brothers, the last year has been all whirlwind, all the time. Yet somehow, on the road to becoming a pop culture phenomenon, the trio never broke a sweat -- other than on the stage, giving their all, and living their dream. If anything, Jonas Brothers have embodied the calm within the storm. And since the release of their 2007 self-titled platinum CD, Kevin, Joe and Nick have used their time wisely. As they prove on their new Hollywood Records CD, A Little Bit Longer, Jonas Brothers have grown exponentially as songwriters, musicians and recording artists."The lyrical content has gotten more in-depth," says Nick Jonas of the new album. "It's about who we are as people and our personal lives, things we've gone through in the past 12 months." That year was about much more than simply handling a media frenzy with grace and humor. The brothers also took stock of themselves. In the new album's 12 songs -- all written by Jonas Brothers -- they put their feelings on the line, while still rocking the house as only they can.Produced by John Fields (with Jon Lind and Kevin Jonas, Sr., serving as executive producers), A Little Bit Longer covers much musical and emotional ground, kicking off with the joyful jam "BB Good." Says Joe of the track, "It's a big sing-along song, and it's fun." The funky and danceable debut single, "Burnin' Up," keeps the party going, with Big Rob, the brothers' hefty security guard, rapping midtrack. "It's about this girl," adds Joe. "Maybe she's at a party, and you feel that immediate connection. You both know it's there."
