Photographer Glen E. Friedman has a new book out in September, ‘My Rules,’ which represents some 30 years and 7 pounds of gorgeous hardcore, hiphop, and skateboarding history. He got together with his old friend Ian MacKaye at Dischord House just outside of Washington D.C. to discuss some of the photographs in Glen’s forthcoming book. Below, a couple of great shots of Minor Threat in the early 1980s by Glen.
