Hails From: Mohnton, Penn.
For Fans Of: The Killers and Nine Inch Nails

Why They're About to Pop: With Innerpartysystem -- named for the class hierarchy in George Orwell's '1984' -- singer Patrick Nissley and drummer Jared Piccone grew their electro-rock outfit from the ashes of their previous band Thirteen Over Eight. Adding keyboardist Kris Barman and guitarist Jesse Cronan, the band was signed to the Stolen Transmission label, which released the group's 'The Download EP' in 2007, before eventually folding into the Island Records roster. Innerpartysystem's self-titled full-length will hit shelves on September 9, and the band is out on tour through August 30 before playing at New Orleans' Voodoo Music Experience on October 25.

Who: Metro Station
Album: 'Metro Station'
Video: 'Shake It'
Hails From: Hollywood, CA
For Fans Of: Motion City Soundtrack and Hellogoodbye

Why They're About to Pop: What does an electro-rock band from California have to do with the Disney Channel's most popular TV show? A lot. In 2006, Metro Station's Trace Cyrus (that's right, Miley's stepbrother) and Mason Musso were brought together on the set of 'Hannah Montana' on which Musso's brother Mitchel also stars. Thanks to the urging of their mothers, Cyrus and Musso bonded over their love of music and soon added Anthony Improgo on percussion and Blake Healy on keys to form the 80s-influenced outfit. Record labels came knocking and the four-piece eventually recorded their self-titled debut album, in part produced by Motion City Soundtrack's Justin Pierre and Josh Cain. Since the release of their record, the band's single, 'Shake It,' has reached No. 10 on the Billboard charts and has been certified gold, selling over 800,000 copies. Metro Station is currently on the 'Soundtrack of Your Summer Tour' with Boys Like Girls and Good Charlotte through August 22.

Who: Lesley Roy
Album: 'Unbeautiful'
Video: 'I'm Gone, I'm Going'
Hails From: Dublin, Ireland
For Fans Of: Pink and Avril Lavigne

Why She's About to Pop: When her 7-year-old peers were playing with dolls and trucks, Lesley Roy received her first guitar and began penning her own songs. Eight years later, she recorded her first demos and started to shape her pop-driven rock sound. Roy was eventually signed to Religion Music in Ireland, but proved to be such a unique talent that Jive Records took interest in backing her debut solo album. Now at the landmark age of 21, Roy has engaged listeners on both sides of the Atlantic with her single, 'I'm Gone, I'm Going,' off her Max Martin-produced record 'Unbeautiful.' You can catch Lesley Roy on tour in select U.S. cities from September 16-28.

Artist: Staind
Song: 'Believe'
Why You Should Watch: After three years, the alternative metal band returns with its sixth studio record, 'The Illusion of Progress,' in stores August 19. Frontman Aaron Lewis shows his softer side as he belts the ballad-like first single along a deserted beach. Buy it on iTunes.

"We haven't played in a couple of months now, so it's good to see you again," Pete Wentz said early in Fall Out Boy's 40-minute set in L.A on Thursday. The band has been busy writing material for the follow-up to last year's 'Infinity on High,' but the combination of Victoria's Secret and the famed Santa Monica Pier was a tough offer to pass up.

The group headlined a free show, Pinkapalooza, against the backdrop of a neon-lit ferris wheel and roller coaster to celebrate Victoria's Secret's new collegiate line. Flanked by Pink banners on both sides, the quartet embraced the spirit of a free show for thousands of fan, giving a shout out to Victoria's Secret in a unique way. Quoting a "friend" in 'Every Time I Die,' Wentz dedicated a song to his friend's two favorite things -- "Boobs."

It was that kind of a loose set, as they teased the Panic at the Disco guys, who're overseas in Europe and jealous of FOB's lush setting, according to Wentz. FOB performed a snippet of Panic's 'I Write Sins, not Tragedies,' as frontman Patrick Stump showcased his softer side, bringing a reggae vibe to Akon's 'Don't Matter,' ending it with the refrain to Sonny and Cher's classic 'I got you Babe.' Then the guitarist asked the crowd, "How retarded it that? Akon to R. Kelly to Sonny and Cher?" Of course, the group gave the fans what they wanted as well, rocking 'This Ain't a Scene, it's an Arms Race." And Wentz promised the absence wouldn't be too painful. "We won't be gone as long as you think."

Who: The Cab
Album: 'Whisper War'
Video: 'One Of Those Nights'
Hails From: Las Vegas, NV
For Fans Of: Fall Out Boy and Panic at the Disco

Why They're About to Pop: The Cab has certainly gotten by with a little help from their friends, and in this case, those friends include members of Panic at the Disco and Pete Wentz. The Vegas five-piece got its start in 2005 when Alex DeLeon (vocals) and Cash Colligan (bass) started making music together in high school. The duo soon added Alex Johnson (drums), Alex Marshall (piano) and Ian Crawford (guitar) to flesh out their bold pop rock sound. After touring locally in Nevada, the Cab's demo landed in the hands of Panic at the Disco's Spencer Smith, who brought the record to Panic's label owner, Pete Wentz. The Cab was then signed to Decaydance/Fueled By Ramen and their single, 'One of Those Nights,' featuring FOB frontman Patrick Stump and Panic's Brendon Urie, has generated a swell of buzz on the Internet. The Cab has toured with the likes of Cobra Starship and We the Kings, and is currently out with the Hush Sound through August 25.

For Fans Of: Daughtry and Flyleaf

Why They're About to Pop: Originally known as Revolution Theory, this rock four-piece got their start in 1997 when its members met in college. With dreams of getting a recording deal, the band moved to New York City where, in effect, their wishes came true. Rev Theory released their debut full-length, 'Truth is Currency,' in 2005, and toured relentlessly with the likes of Fall Out Boy and Evanescence.

Who: Thriving Ivory
Album: 'Thriving Ivory'
Video: 'Angels and the Moon'
Hails From: San Francisco, Calif.
For Fans Of: Coldplay and U2

Why They're About to Pop: Described as "melodic, sweeping and triumphant," Thriving Ivory has enchanted fans from first listen. Upon meeting in college at the University of California, Santa Barbara, lead singer Clayton Stroope and pianist Scott Jason forged an immediate friendship over music. Adding guitarist Drew Cribley, bassist Bret Cohune and drummer Paul Niedermier, the band found themselves playing to upwards of 600 people per night in their first days together. Now after signing a recording contract with Wind-Up, Thriving Ivory is further cultivating their fanbase with their breakout single, 'Angels and the Moon.' Catch the five-piece on tour around the country through August 7.

These are good days for Weezer. More than 15 years since its formation, the band is having the biggest hit of its career with 'Pork and Beans.' That's saying a lot for a group that also brought us the indelibly catchy tunes 'Beverly Hills,' 'The Sweater Song,' 'Buddy Holly' and 'Hash Pipe' over the years.

Led by the enigmatic, reserved Rivers Cuomo, who has collected a degree from Harvard in English literature since the release of the band's last album, Weezer are reveling in their continued good fortune. That includes the No. 4 debut of their new (and third) self-titled album, dubbed "The Red Album" to distinguish it from the "Blue" and "Green" albums.

When asked about the secret behind writing a good power pop song, Cuomo seems to have the process down to a science. "It's different in different decades, but I think now the chorus has to be the best part of the songs," Cuomo tells AOL during the band's recent Sessions taping. "It's gotta be catchy. It's gotta be pretty short but not too short, like, just over 3 minutes is good. You gotta get to the chorus within a minute. For us, major keys are great and the tempo of at least 115 beats per minute."
