Even though Sugarland's latest Mercury Nashville album, "Enjoy the Ride," was only released last fall, singer Jennifer Nettles tells Billboard.com the Atlanta-based duo is already writing material for its next album.

"We started writing and it's much nicer this time," Nettles says. "We're enjoying the ride. Basically, we wrote the last record in about two weeks over the course of three months. We were really under the gun, time-wise. So to have a little bit more time is really a gift."

She adds, "We don't feel every song we write needs to be close to what has to be on the album. Instead, we can be rather creative and see what we want to be on the album."

One new track that has Nettles and bandmate Kristian Bush excited is "Making Space," which she describes as an evolution of the twosome's sound but not so much that "fans will go, 'Who in the hell was that?' I think it's going to be obvious it's us."

While there is no timetable for the next release, there is talk in the Sugarland camp about cutting a holiday-based EP this fall.

"We're throwing around a few ideas for possibly something for Christmas, because we've never done that before and we have a lot of fun, sort of maybe non-traditional numbers we'd like to throw out there," Nettles says. "Creatively, the concept is in motion."

For now though, Sugarland won't be playing any new material until perhaps its first-ever headlining tour, slated for the fall. Currently, the act is opening on Kenny Chesney's massive spring/summer outing. Nettles admits the tour, which stops tonight (May 10) in Grand Rapids, Mich., is one big party both onstage and off.

"It's so fun. Kenny really fosters an environment that is playful, young, hip, warm and welcoming," Nettles says. "It pretty much feels like summer camp."
