There is no sound system whatsoever where the inauguration was held, it would most likely sound horrible and you know people now a days, they would say it was her fault. For example The Black Eyed Peas at the last superbowl everyone says was horrible but they couldn't help all of it becuase a football stadium isn't meant to have huge concerts.
How about fuckin Slayer? These guys are as old as some of your grandparents and they still play like this. Live too!
