Jonas Brothers playing free concert

Will preview songs from fourth album

NEW YORK -- Teen pop sensations the Jonas Brothers will perform a free club concert Thursday at Irving Plaza in New York City.

Admission will be on a first-come, first-served basis. Doors for this all ages show will open at 8 p.m., and the band goes on at 9 p.m. No opening act is scheduled.

The Jonas Brothers will preview songs from their fourth album, "Lines, Vines and Trying Times," which is due in stores on June 15.

"This album is taking steps," Nick Jonas told in March. "We're trying to learn as much as we can, continuing to grow." Kevin Jonas added that "the overall message is its the same old Jonas Brothers, in a sense" but said the group would be "adding more and more music," including horns and strings and "different musical instruments that are going to add and build to the sound we already have."

The show will also preview elements of the group's forthcoming world tour -- the Jonas Brothers World Tour 2009, produced by Live Nation and presented by Burger King -- which will play a handful of dates in South America in mid-May before heading to the U.K. and Europe in early June. The 44-date North American leg begins June 20 at the Dallas Cowboys New Stadium in Texas and wraps Aug. 31 at the Scotiabank Place in Ottawa.
