The guy who made this site refers to himself as "a cultural anthropologist" and spends his time looking for real blues juke joints in the deep south. What's a juke joint? It's the kind of place where the blues was born -- check out the site for more info.Most of us didn't even know these places still existed, given that all the blues bars in the big cities are basically frequented by frat boys!
Spend a few minutes on this site and you'll be ready to plan a road trip/pilgrimage down to the delta...
