“You might say that a people or a movement must be constituted musically before it can be constituted politically.” This was one argument among many declared by Michael Denning, a professor of American studies and English at Yale University, during a talk for his new Verso book, Noise Uprising: The Audiopolitics of a World Musical Revolution. Denning, however, made it clear that the music culture during the brief period of time studied in his book—from the widespread use of electrical recording in 1925 to the early years of the Great Depression—was not revolutionary politically.
