Kristopher Spencer (2008). Film and television scores, 1950-1979: a critical survey by genre. McFarland. ISBN978-0-7864-3682-8. Quotes Skip Heller: "[Jazz] represented something lean, tough, cynical and intelligent; adjectives that applied easily enough to the detectives of these pictures. These guys weren't well described by a soft violin. Instead, the metallic-yet-soulful saxophone summed up this brave new world."
