The stage — specifically, former Naval Air Station Alameda — is set for a one-of-a-kind show this upcoming weekend: “Island City Waterways: Uprooted.” After a two-year hiatus, this popular, free-of-cost outdoor event celebrating the history of the Alameda waterfront returns to the East Bay island on Saturday and Sunday. Presented by the community-based arts center Rhythmix Cultural Works in partnership with the City of Alameda, “Island City Waterways 2022” explores the concept of being uprooted — with a specific tie-in to the history of Alameda’s NAS as an aircraft and pilot hub, military base and “civil control station” where Japanese Americans were ordered to report before being sent to World War II internment camps.
