Book excerpt: Jody Blake demonstrates in this book that although the impact of African-American music and dance in France was constant from 1900 to 1930, it was not unchanging. This was due in part to the stylistic development and diversity of African-American music and dance, from the prewar cakewalk and ragtime to the postwar Charleston and jazz. Successive groups of modernists, beginning with the Matisse and Picasso circle in the 1900s and concluding with the Surrealists and Purists in the 1920s, constructed different versions of la musique and la danse negre. Manifested in creative and critical works, these responses to African-American music and dance reflected the modernists' varying artistic agendas and historical climates.
