Alan Lomax (January 31, 1915 – July 19, 2002) was one of the great American field collectors of folk music of the 20th century. He was also a folklorist, ethnomusicologist, archivist, writer, scholar, political activist, oral historian, and film-maker. Lomax also produced recordings, concerts, and radio shows in the U.S and in England, which played an important role in both the American and British folk revivals of the 1940s, '50s and early '60s. During the New Deal, with his father, famed folklorist and collector John A. Lomax and later alone and with others, Lomax recorded thousands of songs and interviews for the Archive of American Folk Song at the Library of Congress on aluminum and acetate discs.

After 1942, when Congress cut off the Library of Congress's funding for folk song collecting, Lomax continued to collect independently in Britain, Ireland, the Caribbean, Italy, and Spain, as well as the United States, using the latest recording technology, assembling a treasure trove of American and international culture. With the start of the Cold War, Lomax continued to speak out for a public role for folklore, even as academic folklorists turned inward. He devoted much of the latter part of his life to advocating what he called Cultural Equity, which he sought to put on a solid theoretical foundation through to his Cantometrics research (which included a prototype Cantometrics-based educational program, The Global Jukebox). In the 1970s and 80s Lomax advised the Smithsonian Institution's Folklife Festival and produced a series of films about folk music, American Patchwork, which aired on PBS in 1991. In his late seventies, Lomax completed a long-deferred memoir, The Land Where the Blues Began (1995), linking the birth of the blues to debt peonage, segregation, and forced labor in the American South.

Aaron Copland ( /ˌærən ˈkoʊplənd/; November 14, 1900 – December 2, 1990) was an American composer, composition teacher, writer, and later in his career a conductor of his own and other American music. He was instrumental in forging a distinctly American style of composition, and is often referred to as "the Dean of American Composers". He is best known to the public for the works he wrote in the 1930s and 1940s in a deliberately more accessible style than his earlier pieces, including the ballets Appalachian Spring, Billy the Kid, Rodeo and his Fanfare for the Common Man. The open, slowly changing harmonies of many of his works are archetypical of what many people consider to be the sound of American music, evoking the vast American landscape and pioneer spirit. However, he wrote music in different styles at different periods of his life: his early works incorporated jazz or avant-garde elements whereas his later music incorporated serial techniques. In addition to his ballets and orchestral works, he produced music in many other genres including chamber music, vocal works, opera and film scores.
