Sean Duffy was the head of Last Rites fanzine and Last Rites promotions. The former released some well-known fanzines and mixtapes, including the Code Blue compilation. The latter was Duffy's promotion company that put out a large number of punk shows in the mid-to-late 1980s. Though he isn't incredibly well-known, Duffy's promotions and ability to book national acts made him one of the most important contributors to the 1980s Chicago punk scene. Duffy was also the manger for a few bands (Loudmouth, Wickerman) and as of 2001, was the booking manager for the Abbey Pub.
