Michael Broyles shows how three key decades—the 1840s, the 1920s and the 1950s—shaped America’s musical future.In each, new styles of music combined with emerging technologies, from the locomotive to the transistor radio, to have lasting impact on our cultural landscape.All too often, these new developments revealed racial fault lines running through the business of music in an echo of American society as a whole.Through the music of each decade we see the social, cultural and political fabric of the time.A variety of characters serve as focal points for each chapter, including the original Jim Crow, a colourful Hungarian dancing master named Gabriel De Korponay, “Empress of the Blues” Bessie Smith, and the singer Johnnie Ray, whom Tony Bennett called “the father of rock ‘n’ roll.” Their stories, and many others, animate this fascinating look at how American music became what it is today.
