If you're not a tween/teenage girl or don't live in proximity to one, you might not yet be in on the phenomenon created by 20-year-old Kevin, 18-year-old Joe and 15-year-old Nick. They opened for Miley Cyrus on her fall Hannah Montana tour to the delight of shrieking girls everywhere. Their song S.O.S. catapulted to No. 1 on iTunes. Their second album has sold more than 900,000 copies.
Last month, the band became the youngest act to sign a deal with concert presenter Live Nation. The multimillion-dollar, two-year pact includes promoting 140 shows in theaters and arenas worldwide by the New Jersey-based brothers in Arizona.
"We know where we're going to be at the end of 2009," Joe said incredulously.
Though some might consider putting such big money behind a still-developing act as risky, Billboard 's Ray Waddell calls it a smart move: "The Jonas Brothers are about as safe a bet as exists in the music business today."
Indeed, the band's three shows at the Gibson Amphitheater in Universal City, Calif., set a record for the fastest sellouts in its 35-year history when the first two shows sold out in two minutes. Even the brothers admit they can't wrap their heads around the Live Nation deal.
"In a weird way, it's humbling," Nick said.
All this success comes after the band got off to a rocky start. Its debut album came out on Columbia in 2006 to little fanfare because their primary champion, Columbia President Steve Greenberg, had departed the label by the time it was released.
The band soon parted ways with Columbia and signed with its current home, Hollywood Records. (The album, It's About Time , is now a collector's item with an asking price of up to $299 on Amazon.com).
The comparisons with Hanson are inevitable: like Hanson, these three brothers write their own songs and play their own instruments, giving them more credibility than the average boy band. (The Jonas Brothers even mention Hanson in their song That's Just the Way We Roll .) Though their songs are solid power pop, they possess more of a rock edge than those by many of their contemporaries.
The tour is the first step toward global domination that Hollywood Records parent, The Walt Disney Co., which has provided in the past for such acts as Hilary Duff, Miley and the cast of High School Musical , all of whom have enjoyed platinum and/or multiplatinum success.
Though mainstream radio has been largely resistant to these acts, there are signs that the Jonas Brothers will break through with new single When You Look Me in the Eyes , which is already receiving airplay on pop stations in New York and Los Angeles.
"The only way to get onto pop radio is to make records with broad appeal. They have begun to do that," Mr. Greenberg says. "This is different from being big in Disney's proprietary media, where super-serving the core young audience is all that matters."
Not that the Disney juggernaut will stop any time soon. In mid-June comes Camp Rock , a Disney Channel movie which the network hopes will be the next High School Musical . The next month, the band is due to release its third album.
