JOBROS ACE SLOW JAMS

Jonas Brothers, "Lines, Vines and Trying Times" (Hollywood Records)

Yes, millions of teenage girls helped the Jonas Brothers rise to fame, but they're also the reason why the group isn't taken seriously, musically speaking.

The musicianship of Nick, Kevin and Joe is often overlooked, but that may finally change on their fourth studio album, "Lines, Vines and Trying Times."

The follow-up to their breakthrough CD, 2008's "A Little Bit Longer," "Lines" features a cool collection of songs primarily written by the JoBros, including groovy ones like "Hey Baby," "Much Better" and the first single, "Paranoid."

But the best songs are the slow jams, such as "Turn Right" and the exceptional "Black Keys," solely written by the youngest Jonas, 16-year-old Nick.

The CD is produced by John Fields (Miley Cyrus, Switchfoot) and executive produced by poppa Jonas, Kevin Jonas Sr.
