Well the citizens of Chicago must have succeeded in doing good things, because the "Go Do Good" mural has been removed.  In its place, is now a colorful portrait of Chicago Blues icon Muddy Waters.  To me, it is a far more appropriate image for the space and the City.  Although I might have preferred a more subtle depiction of Muddy.  It instantly brings to mind Muddy's controversial 1968 album on Chess entitled Electric Mud.  Muddy did not need to go psychedelic.  He was the one who paved the path that made a lot of the rock music of the late Sixties possible.
