One of the foremost chroniclers of American working class life through song, Guthrie has exerted a profound influence on folk and rock musicians from Bob Dylan to Wilco. Among Guthrie's most well-known songs are "Pastures of Plenty," "Bound for Glory" and "This Land is Your Land," the latter of which, by virtue of its popularity, has become something of an "alternative national anthem" in the United States. - Library of Congress
