Selecting material mostly from the pages of Sing Out! magazine, Pete Seeger performs 20 "contemporary topical and political songs," as Folkways Records head Moses Asch puts it, with "contemporary" defined as the 25 years leading up to the album's 1958 release date. Annotator Irwin Silber, who was also editor of Sing Out!, calls the result a "living newspaper of history."[4]
