According to the artist Dennis Stock, "I had a passion for jazz. I had listened to and attended many jazz sessions from child onwards. So I went out for three years and explored the world of musicians all across the United States and had a wonderful time. It was joyful. Just marvelous".

He also says quote, "Improvisation, the essence of their art, dictated the form of this book. It often happened quickly; the photographic decision, like the jazz decision, must be instantaneous".
