Sure, it seems a bit counter-intuitive. How could the favorite subject of protest music also be its greatest protector? Well, believe it. If it wasn't for Alan Lomax and the Archive of American Folk Song at the Library of Congress there might not be a Woody Guthrie — and thus by extension — a Bob Dylan or a Bruce Springsteen, and well … you get the rest. In March 1940, Lomax arranged for Guthrie to travel to Washington, D.C. to record traditional ballads and his original songs at the Department of the Interior recording lab. What emerged from three days of sessions is one of the purest documents of Americana ever released.
