I saw Bon Jovi 30+ years ago, before anyone knew who they were (opening for the Skorpions)
The sound guy did them so dirty.... All you could hear was bass and drums, after they got pelted with beer bottles for 20 minutes, they bailed out.... I remember thinking "Probably never hear from those guys again"
Some of us still go to live music to listen to it, and don't want to hear people talk. I mean I really hate it, actually.
I realize people have been talking about vastly different kinds of music events in this thread, though. So if you're talking over someone doing acoustic air supply covers at a winery somewhere, just carry on. You're probably not bothering anyone.
