Dark Hollow is a project inspired by Dion's home state of Tasmania, Australia, and is dedicated to supporting the future of the Tasmanian Wilderness. Featuring the illustrations of LA artist Nathan Kostechko. Dion stated: "Joe G and I have been working on Dark Hollow for the past few years. It's grown and evolved over time, but it has always taken its core inspiration from my home state of Tasmania. The film is our vision of how the world could be if we looked after it, and features appearances from some of my best friends, including Craig Anderson and Chippa Wilson."
