Holden's professional clients—City Paper was one of many, including not only other newspapers and magazines, but record labels (Dischord, Sub Pop) and bands (Linkin Park, The Ramones), television and film companies (A&E Network, Paramount Pictures), banks and other companies (M&T Bank, Audi, PRS Guitars)—were part of many overlapping circles in his life. As the son of Todd Holden—a photographer, journalist, and nature-lover who the Harford County Council dubbed a "living treasure" in 2012—he got honorary acceptance wherever his dad went. As a rock drummer, he had bandmates and fans from his current acts (Pearly Goats, Imperial Tramp) and those of his past, like Spot and Chaser. As an avid motorcyclist, he knew many who shared the thrill of riding fast on two wheels. As an artistic nude photographer, he dealt discreetly with many models of diverse backgrounds and limited inhibitions. As an instructor of photography at Towson University and Notre Dame of Maryland University, he likely inspired students with his mastery of photographic gadgetry—and the importance of analog in the digital age.
