Fall Out Boy guitarist Joe Trohman is a serious metalhead, but he keeps his head-banging riffs in check on the band's latest and poppiest effort yet, Folie A Deux. "For me to insert Randy Rhoads licks into Fall Out Boy's music would sound crazy," he says. Even so, he adds grit and gusto to each track - even some dirty blues on the breakout hit I Don't Care. In this exclusive interview, Trohman talks about Fall Out Boy's rapidly changing musical landscape, the pressures of celebrity and how a lover of Slayer has sold millions in the world of emo.
