Established in 1935 under the aegis of the Works Progress Administration, the Federal Music Project (FMP) was designed to employ musicians who were hard hit by the economic devastation of the Great Depression. All of This Music Belongs to the Nation is the first book-length study of the FMP and the many paradoxes and conflicts that marked its four-year existence.
As Kenneth J. Bindas points out, the FMP leadership was more conservative than that of the sister projects in art, theater, and writing. Its stated aim of "raising" the taste of musicians and citizens alike created a particular problem. Although many unemployed musicians came from the sphere of popular music, such as jazz and Tin Pan Alley, the FMP chose to emphasize "cultured" music, particularly the orchestral works of composers in the European classical tradition. Inevitably, this created tension within the project, as those musicians deemed "popular" received second-class treatment and, in the case of racial and ethnic minorities, were segregated and stereotyped. Despite these troubles, Bindas demonstrates, the FMP succeeded in bringing music to millions of listeners across the country.

At its peak the Federal Music Project (FMP) employed nearly 16,000 people who reached millions of Americans through performances, composing, teaching, and folksong collection and transcription. In Sounds of the New Deal, Peter Gough explores how the FMP's activities in the West shaped a new national appreciation for the diversity of American musical expression.
 
From the onset, administrators and artists debated whether to represent highbrow, popular, or folk music in FMP activities. Though the administration privileged using "good" music to educate the public, in the West local preferences regularly trumped national priorities and allowed diverse vernacular musics to be heard. African American and Hispanic music found unprecedented popularity while the cultural mosaic illuminated by American folksong exemplified the spirit of the Popular Front movement. These new musical expressions combined the radical sensibilities of an invigorated Left with nationalistic impulses. At the same time, they blended traditional patriotic themes with an awareness of the country's varied ethnic musical heritage and vast--but endangered--store of grassroots music.
