Director Steven Cergizan began compiling interviews for this Chicago hardcore-punk documentary back in 2010, and his efforts pay off. Immersive and authoritative, this captures the big-picture ideas that have made local hardcore unique since the late 80s. Longtime scene veterans (Jeff Jelen, Aaron Aspinwall), hardcore icons (Martin Sorrondeguy, Ebro Virumbrales), and international rock stars (Tim McIlrath of Rise Against, Andy Hurley of Fall Out Boy) set up Cergizan’s cornucopia of archival footage, and though the dense history can detract from the movie’s momentum, the story’s girth underscores the notion that Chicago hardcore feels as big as the world—and that it’s still alive.
