Fall Out Boy was formed in 2001 in the Chicago suburb of Wilmette, Illinois by friends Pete Wentz and Joe Trohman. Wentz was a "visible fixture" of the relatively small Chicago hardcore punk scene of the late 1990s, performing in various groups including the metalcore band Arma Angelus. Wentz was growing dissatisfied with the changing mores of the community, which he viewed as a transition from political activism to an emphasis on moshing and breakdowns. With his enthusiasm in Arma Angelus waning, he created a pop punk side project with Trohman. Trohman met Patrick Stump, the drummer for grindcore band xgrinding processx
