Mentioned during this show: I won't dignify Quechup.com with a link, and once again, I urge you to stay away from them and their questionable business practices; if you want a cool t-shirt, visit ElectroFi.com, although when I visited on 9/8/07, the site was down temporarily.

Excellent online resources for more information about the blues: The Blues Foundation and the Delta Blues Museum; and be sure to download and listen to the DBM's top-notch (and free) podcast, the Uncensored History of the Blues. Be sure to read Today's Chicago Blues by Karen Hanson, an excellent guide to all things blues in present-day Chicago.
