Worst audio ever.  Saw David Sedaris read and take q/a.  Whoever was responsible for the audio check should be moved to another department.  Two minutes into his first reading the audience started pleading for some improvement in the audio.  Sedaris was unaware that sound was terrible.  After a weak attempt by the audio folks we all endured an evening of the worst echo and sound at any event.  My wife and were looking forward to this evening having bought our tickets 10 months in advance.  It will be a long time before we consider going back to Gammage.
