In early 2009 the four members of San Diego’s Allstar Weekend drove up to Los Angeles to hand out flyers outside the premiere of “Jonas Brothers: The 3D Concert Experience.” A little over a year later, the band’s high-energy pop-punk single “A Different Side of Me” had sold over 100,000 copies and topped Radio Disney’s Top 30 Countdown.

Allstar Weekend’s speedy ascent to stardom might come as a surprise, but the band’s proximity to its roots makes its songs utterly irresistible. “With Allstar Weekend, what you see is what you get,” Porter explains. “We do all the things that normal teenagers do, and that’s exactly what we write our songs about.”

Allstar Weekend’s aptly titled debut, “Suddenly,” shows off that appeal. From “Hey Princess,” the set’s lovesick opener, to “The Weekend,” its exuberant closer, these seven tracks serve as a relentlessly catchy dispatch from the front lines of the American adolescence.  “We worked our butts off to make this record the best we can, and we’ve worked our butts off to put together a great live show,” says Porter with visible enthusiasm. “We can’t wait to just get out there and play our new songs for our fans.”
