The Chicago Blues Hall of Fame website has a few cool videos worth watching. You'll find a couple by Elmore James Jr., recorded a few years back at The Big O bar and the Keynote Lounge (Chicago Southside clubs). Also Sexie Jamie, a featured artist with the Broomdusters Blues band, singing Wang Dang Doodle. Plus, vids with Vance Kelly and Magic Slim.

They're pretty good quality -- decent sound and lighting. I think you'll enjoy them.

I don't know what's going on with the Chicago Blues Hall of Fame organization and their website. The last updates were over a year ago, so it's a little neglected.
