The Good News from the Chicago Jazz Festival:  Legendary drummer, percussionist, and nice guy Avreeayl Ra was back in the saddle tonight, after having been jumped and then beaten by a group of thugs as he walked to the parking lot from Chicago's Green Mill Jazz Club a couple of weeks back.  From my seats, he looked fully recovered, but my photographs reveal some purple bruising around his left eye. He was in excellent form and spirits.
