Just after World War II, American composers and jazz performers were interested in indeterminacy and improvisation. Yet the composers tended to deny the influence or importance of jazz in a tacit move to keep their music "pure" of associations with racial protest then emanating from the jazz sphere. Lewis identifies John Cage and Charlie Parker as representatives of "Eurological" and "Afrological" approaches, respectively, whose differences turn on their attitude toward the expression of race, ethnicity, class, and political ideology in music.
