Fall Out Boy [SEP] 2010–2012: Hiatus and side projects
He also formed heavy metal outfit The Damned Things with Trohman, Scott Ian and Rob Caggiano of Anthrax, and Keith Buckley of Every Time I Die. Despite this, the members all remained cordial to one another; Wentz was Stump's best man at his wedding. The hiatus was, all things considered, beneficial for the group and its members, according to Hurley. "The hiatus helped them all kind of figure themselves out", he explained in 2013. "Especially Joe and Patrick, who were so young. And Pete is a million times better."
