If you happen to be a Fall Out Boy hater, an early six-word proclamation from Pete Wentz was likely more chilling than a tornado siren. Then again, if you happen to be a Fall Out Boy hater, you were also likely nowhere near the Marcus Amphitheater Saturday night, where the pop/punk rockers teamed up with Paramore. It's too bad because the duo put on quite the show, a nearly four-hour burst of music that left the crowd happily exhausted.
