Long before his pandemic-era side project Militarie Gun became a big band, Ian Shelton started the West Coast powerviolence outfit Regional Justice Center for a very specific reason. Ian’s younger brother Max was sent to prison for assault, and the RJC project, named after the facility where Max was incarcerated, was about the causes and effects of that kind of incarceration. Sometimes, Max added lyrics of his own. Now, Max is out of prison, and he’s the new singer of Regional Justice Center.
