Fall Out Boy just released "Young Volcanoes," another track from their much anticipated comeback album Save Rock and Roll, out April 16. This time the Chicago boys scale back the rock aggression in favor of an incredibly catchy acoustic riff and arena-filling chorus. "We are wild / We are like young volcanoes," singer-guitarist Patrick Stump wails. Commit this one to heart—fans will be singing it at every stop on FOB's fall tour.
