Jules Allen spent five years traveling the country photographing African-American marching bands. What he saw through his lens was “a precision art form” as public spectacle and a culture that “breathes the soul and spirit of Africa within the modern world.” The result is the simply titled “Marching Bands.” It's the fourth book by the long-time Queensborough Community College art and design professor, whose photographs are in the permanent collections of the Museum of Modern Art, the Smithsonian and the National Gallery.
