In a recent interview with LiveDaily, Fall Out Boy [ tickets ] bassist Pete Wentz said the band is playing clubs to warm up fans for its forthcoming album, "Infinity on High," because it didn't want to seem cocky by immediately jumping to arenas. But Fall Out Boy's talent--particularly Patrick Stump's stellar vocals and guitar playing, and Wentz's nimble bass technique--is screaming for an arena-sized audience.

Stump played intricate riffs while singing to an impeccable standard during Fall Out Boy's show Saturday (1/6) at Tempe, AZ's Marquee Theatre. Meanwhile, Wentz proved that original bass-playing styles can still be found and thrown into the mix; he seemingly strums all of the strings while still picking out the correct notes, while spinning around like a 6-year-old child.

Fall Out Boy's performance during the third show of the Friends or Enemies tour--which also includes New Found Glory, Permanent Me and The Early November--primarily featured songs from the group's sophomore release "From Under the Cork Tree." The show kicked off with Wentz shrouded in a hoodie, much to the dismay of the teenage girls in the audience, during the song "Our Lawyer Made Us Change the Name of This Song So We Wouldn't Get Sued." Wentz spun around so vigorously that, when he landed in front of a wall of amps, he nearly tripped during "Of All the Gin Joints in the World."

Wentz later removed his hoodie, stood atop a monitor and asked the audience to take a step back because the fans in the front of the venue were being pushed against the barricade. He shared his trademark humor, however, to introduce "Sugar, 'We're Going Down."

"We've been playing a lot of radio shows with people like Nick Lachey, and we've been hearing songs about falling in love and getting married," he said." That's not what this song is about. It's about one girl and one night."

He also poked fun at a fan who threw a shoe at him. "Cinderella, where the f--- are you?" It turned out to be a female fan, whom Wentz then invited on stage.

"A Little Less Sixteen Candles, A Little More 'Touch Me'" was supercharged with Wentz and guitarist Joe Trohman jumping off of monitors and drummer Andy Hurley pounding away. A few songs later, Wentz acknowledged his female fans.

"'We applaud all the girls who come for the music or who play in band," he said. "You don't have to be a coat rack for some boy."

Fall Out Boy used the occasion to debut a new song off "Infinity on High," a tune called "Thriller," the studio version of which features Jay-Z. The band ended the set with "This Ain't a Scene, It's an Arms Race" also from the forthcoming album, due Feb. 6.

For the encore, New Found Glory guitarist Chad Gilbert joined the band on vocals for "I Slept With Someone In Fall Out Boy And All I Got Was This Stupid Song Written About Me." The encore also included FOB's second hit, "Dance Dance."
