David Gahr was one of music’s renowned but under-the-radar photographers. Starting in 1958when Moses Asch of Folkways Records brought his work to a larger audience, Gahr captured iconic images of some of the greatest musicians of the twentieth century, including Bob Dylan, Pete Seeger, Janis Joplin, Johnny Cash, and Miles Davis, to name only a few. Chris Murray is a writer and founder of Govinda Gallery, which represents some of the best rock music–related fine art photography and photographers in the world.
