Rockin' bros — the Jonas Brothers

When the Jonas Brothers hit the E Center stage tonight, there will be a lot of happy people.

Not only will the fans of the nearly sold-out concert be screaming for Kevin, Joe and Nick Jonas, but the three teen idols are almost as excited to play as the fans are to see them.

"The stage is unbelievable," said Joe Jonas during a music-critic teleconference two weeks ago. "We showed up for rehearsal the other day to see what the stage is like, and we freaked out."

"This is actually the first time we have some type of production," Kevin Jonas said. "There will be more than just three risers."

While the production is a big part of the show, the band also focuses on the music, Nick Jonas said.

"(We) want to introduce new styles of songs and different types of music into our performance," he said. "So you might hear something and not recognize it right away, but then, all of a sudden, realize that it's a song we've been playing for five years now. We really wanted that for our fans and wanted that for the show.

"We're playing a lot of songs," said Nick. "I have to remember a lot of lyrics. I've been studying and getting them into my memory. And we're also doing a cover of (A-ha's) 'Take on Me.'"

The boys are also playing an excerpt from an Elvis Costello number — "(I Don't Want to Go to) Chelsea."

"We're excited about this because it leads into this awesome amazing drum intro and I'm very excited to be able to put that into our show," Kevin said.

It's no secret that the Jonas Brothers have a lot of musical influences. The three grew up in New Jersey, the home of Bruce Springsteen, Bon Jovi, Frankie Valli and Whitney Houston, to name a few. The brothers have also cited Prince and the Beatles as their main musical influence, as well. And while the Jonas Brothers' fan base consists of young teens, the Jonas Brothers feel it's important to educate their younger fans regarding timeless rock music.

"We think it's really cool to be able to introduce rock 'n' roll to younger fans," said Nick. "And, you know, the parents get into it because (our songs) do sound like the things they used to listen to when they were young. We try to write songs like the great music we listened to."

In addition to reworkings of older songs and adding covers, the trio said they would perform four new songs from the yet-untitled album to be released this year.
