This trip to Africa under the auspices of the American Museum of Natural History, which lasted approximately three months, allowed Boulton to collect musical instruments and recordings from the indigenous populations of Egypt, The Sudan, Uganda, Kenya and Tanganyika.

[1] Over the next 50 years, Boulton participated in dozens of international expeditions, compiling extensive collections of field recordings, films, photographs, and musical instruments.

[1] Boulton was to publish many articles and films, and helped to produce a multitude of museum exhibits related to the artifacts and data she gathered during her research.

The goal of the wartime series was as a morale booster, that would "... broaden awareness of Canada's cultural mosaic, in order to create a feeling of national unity.
