Cameron Crowe’s cult classic Almost Famous is a deep dive into the rock and roll lifestyle-the arrogance of the band waiting to breakthrough and the super fans that throw themselves at their feet. But it’s really about the music lover who devotes his career to its very dissection — the critic. The film follows William Miller on assignment for Rolling Stone, following the sage advice of legendary critic Lester Bangs along the way. So, how true to the rock life is the film? Who would know better than our own resident rock critics, Sound Opinions’ Jim DeRogatis and Greg Kot. Almost Famous is the featured film next Tuesday for Sound Opinions at the Movies at Millennium Park. The rock guys share their reflections on the film.
