Jonas Brothers Talk Fans, Playing New Music on Live Tour 2013 in Radio Disney Interview Before Opening Show in Chicago [LISTEN]

As the Jonas Brothers prep for their upcoming Jonas Brothers Live Tour 2013, which begins tomorrow in Chicago, they're reflecting on how their music and fans have changed over the last few years and what, exactly, audiences can expect on the "Pom Poms" band's first concert series in three years.

In an interview with Radio Disney yesterday (July 8), Kevin Jonas remarked on how their fans have aged with the group since their debut eight years ago.

"[It's the] attitude, you know? It's definitely cool to see some familiar faces we haven't seen in years," he said. "Really, it's because we haven't toured in South America or done a show in New York and finally doing it again and seeing they're much older. You hear their stories of them in college and you're remembering seeing them at concerts so young. So, it's a cool thing. You grow up with your fans."

As fans already know, new music from the "First Time" band's upcoming untitled fall album will be debuted during the Jonas Brothers Live Tour.

"We're just looking forward to being able to play the new music and we're really building the show right now," said Kevin in regards to putting set lists together. "It's going to be something special. We have a lot of music, a lot of content. Years of albums and songs; trying to consolidate that into an hour, 45, or two hour show is kind of difficult."

The band collectively decides what to play on tour but admitted that it's a process of trial and error. In addition to brand new music, fans can mostly expect more recent JoBros material. Joe Jonas admitted that he doesn't remember the words to a lot of their older songs, such as "Kids of the Future" or "Poor Unfortunate Souls."

As with any new JoBros interview, they addressed their album which will come out in the "Fall-ish." "[It's] really exciting for us. The upcoming album is a big step for us musically, a lot of different influences. Stuff you can dance to, stuff you can sing along to, just overall, a really fun vibe I think," said Nick Jonas.
