The Jonas Brothers' time on the blockbuster Hannah Montana/Miley Cyrus arena tour came to an end last night at the Times Union Center Albany, N.Y., but the sibling pop trio doesn't plan to slow down anytime soon.

"There's not a single day when we're not doing something," Kevin Jonas told Billboard in November. "Our goal is to never stop and to get it while it's hot."

The Jonas Brothers -- Kevin, 20; Joe, 18; and Nick, 15 -- will immediately head to an undisclosed Los Angeles recording studio to put the finishing touches on their forthcoming album, which was recently recorded on a Gibson Guitar-branded tour bus, according to a spokesperson at Hollywood Records. The set will likely be released this summer.

During a November tour stop at Los Angeles' Staples Center, producer John Fields (Jimmy Eat World, Pink), who produced the Jonas Brothers' most recent self-titled album, described new songs as "getting a little darker" but "still super pop hits."

Kevin Jonas agreed, saying, "We're a bit older. We've had some painful moments in the last year. A lot of friends stab you in the back. And girlfriends break up with you, or you break up with a girl -- it's terrible what the road will do to you."

Jonas added, "We struggled last year, so we write that into our music. You'd never think on a first listen that "S.O.S." is about somebody walking on broken glass because their heart is hurting so bad."

The group's self-titled set, released in August 2006, has sold 875,000 units in the United States, according to Nielsen SoundScan.

Upcoming plans also include the launch of single "When You Look Me In the Eyes," which will be performed live for the first time Jan. 21 on "The Ellen DeGeneres Show." The song's music video, which features the band in a day-in-the-life setting, is scheduled to premiere around the same time, according the Hollywood Records.

January plans originally called for the Jonas Brothers to begin filming their Disney series "J.O.N.A.S.," but that has been pushed back as a result of the ongoing writer's strike. However, the act's Disney movie "Camp Rock" is expected to break next summer. The brothers have also made past appearances on the "Hannah Montana" show.

Meanwhile, the Jonas Brothers recently inked a two-year, multi-million dollar worldwide touring deal with Live Nation. The agreement is expected to result in more than 140 theater and arena dates during the span of the deal. The band will head back on the road at the end of this month.

Amid their nonstop schedule, the Jonas Brothers have still found time to reflect on their recent experience on the Montana/Miley Cyrus Best of Both Worlds tour. "You hear about the craziness, then you live it," Jonas explained. "I think we were definitely part of history on this tour."
