Pearl Jam is one of the most peculiar bands in rock history. They came into the spotlight in the early 90s, became famous, were called sellouts, then spent the next few years trying to ruin their own reputation. To mark the incredible 20-year journey through success and chaos, Director Cameron Crow whittled down more than 1,200 hours of footage into 120 minutes of live footage and interviews in the documentary Pearl Jam 20, which is at the Michigan Theater on September 20. $9. 7 and 9:45pm. 603 E. Liberty St. 734-668-8397. www.michtheater.org.
