Folk music is more than an idealized reminder of a simper past. It reveals a great deal about present-day understandings of community and belonging. It celebrates the shared traditions that define a group or nation. In America, folk music--from African American spirituals to English ballads and protest songs--renders the imagined community more tangible and comprises a critical component of our diverse national heritage.   In "I Hear America Singing," Rachel Donaldson traces the vibrant history of the twentieth-century folk music revival from its origins in the 1930s through its end in the late 1960s. She investigates the relationship between the revival and concepts of nationalism, showing how key figures in the revival--including Pete Seeger , Alan Lomax, Moses Asch, and Ralph Rinzler--used songs to influence the ways in which Americans understood the values, the culture, and the people of their own nation.   As Donaldson chronicles how cultural norms were shaped over the course of the mid-twentieth century, she underscores how various groups within the revival and their views shifted over time. "I Hear America Singing" provides a stirring account of how and why the revivalists sustained their culturally pluralist and politically democratic Americanism over this tumultuous period in American history.
