Well, mah son, you have, eh hah..., come to the run place, ye see. We ah a collection, if you will, a collection of ol' Delta bluesmen...we got da fire, da fire of th' Delta in our blood, and most of us, huh, came up in the Depression. So, sit back right there, and lemme pluck out a yarn for ya, here, hold on....

Delta blues, Woody Guthrie, big band jazz...

What I would do if I were you, go buy the soundtrack to the movie, "O Brother, Where Art Thou?". Listen to the music, research the artists, find their connections, etc. It's a great album and a general base for Depression-era music.
