O'Brother, Where Art Thou? - WEZY Radio station location

WEZY is the radio station location where Everett, Pete, Delmar and Tommy record "Man of Constant Sorrow". They sing for the blind man (Stephen Root) and receive money to travel with. The four also run across Pappy O'Daniel (Charles Durning) who is walking into the station to broadcast his message for re-election as Mississippi's Governor.
