'Some of These Days' shows how interwar European audiences, artists, and intellectuals particularly associated with modernism, used Black American culture - for which 'jazz' was often a shorthand - to negotiate the disorientating experience of modernity and modernization. One manifestation of this process was the fashionable Negrophilia of the 1920s, the decade in which the two most successful Black American stars of their era first made their names: Josephine Baker and Paul Robeson. The book is threaded around their careers, their travels, and their relationships.
