Nevertheless, I wish the people who wanted to talk constantly, over the music, with their "outside voice" would choose a spot where I couldn't hear them. It's just common courtesy.
The wildest episode I've ever seen at a jazz concert happened at a Pat Metheny Group show at the College of DuPage, near Chicago. It was during Richard Bona's solo feature, which also happened to be the quietest part of the entire show. Just vocal and kalimba. We became aware that someone among us was carrying on a conversation in full voice. People in our area were looking all around for who it was. Finally we realized that the voice was coming from a window above and behind us; some kind of a control booth. It fell to the guy sitting directly under the window to put a stop to it; however, it was too far up for him to even reach. So he tossed his program through the window. Next thing we know, the person doing the yapping is threatening us all with physical violence: "Who threw that shit?!? Why don't you come up here and try that! I'll kick yer fuckin' ass!" and so on. The dude who threw the program said, rather dryly, "Come on down."
Unbelieveable.
