Chris Barnes is a pianist and songwriter who records as Gem Club; Charlie Engman is a photographer and filmmaker. Chris and Charlie have been collaborators since around 2011, starting with, as they tell the story, a set of press photos that ended in a federal arrest, and continuing through music videos for Gem Club’s songs “252,” “Polly,” and most recently “Aperture.” On the release day of Gem Club’s new album, Emerald Press, the two caught up about it all over Google Meet.
