Courtesy of Jack Gallagher It was nearly 3 years ago when comedian and storyteller Jack Gallagher crashed into a car in Sacramento, receiving a traumatic concussion. Since then, Jack has reflected a lot on his life and developed an extremely popular one-man show at the B-Street Theatre. “Concussed” is a one-hour deep dive into the four days after Gallagher’s accident, where he sat in a dark room with no distractions. It was a time for him to contemplate on language and his memories. Gallagher returns to Insight midway through the show’s run at B-Street. "Concussed: Four Days in the Dark" will be available through April 16.
