Whether as an instrument of blatant propaganda or as a means of entertainment, recuperation, and uplift, music pervaded homes and concert halls, army camps and government buildings, hospitals and factories. A medium both permeable and malleable, music was appropriated for numerous war-related tasks. Indeed, even more than movies, posters, books, and newspapers, music sounded everywhere in this war, not only in its live manifestations but also through recording and radio. So far as the U.S. is concerned, even today, musicians such as Dinah Shore, Duke Ellington, and the Andrew Sisters populate the sonic imaginary of wartime. Whether performed by “all-girl” groups such as the International Sweethearts of Rhythm or by military bands conducted by Glenn Miller and Artie Shaw, swing and boogie-woogie entertained civilians at home and G.I.s stationed abroad.
