"For the first half of this country!s existence, our folk song heritage could be traced directly to British peasant culture. Early in the 20th century, musicologists began taking note of such distinctly American musical genres as the Negro spiritual and the cowboy song. When recording became popular in the 1920s, these two styles, now known as race and hillbilly music, established themselves as surprisingly profitable forms of musical expression". (Reader's comment)
