Northern Arizona musician Klee Benally has a new acoustic album out called The Unsustainable Sessions. It’s a departure from the music he’s perhaps best known for, the all-sibling Navajo punk trio Blackfire. But it’s equally powerful in its messages of environmental and social justice. In the latest installment of KNAU’s series Eats and Beats: Stories about Food and Music on the Colorado Plateau, Benally talks about the new album and punk rock as a tool for social change. He’ll perform at an album release party Fri, Dec. 20 at the Coconino Center for the Arts in Flagstaff as part of A Winter Solstice Indigenous Acoustic Revue.
