The Musicians
Let’s not forget the musicians… technically also concert goers, though they are onstage, forced to wear penguin suits or pretend are going to a funeral. They have a pretty cool job—they get to play music for a living. But so many of them are cynical and depressed—they hate rehearsals, and they “don’t really listen to music any more because they play so damn much of it,” to quote a San Francisco Symphony Musician. They, like everyone are waiting for the concert to be over so they can go drinking.
