Man I had a experience like that who loved the contem. scene and he loved bands like Demon Hunter, Skillet, Thousand Foot Krutch, etc... but he constantly was turning me off
so I went and asked him if he had me turned off and he said "no I just have you turned down because I want to hear my daughter."
His daughter lets just say didn't quite have the kind of gift that needed miced. They were such a nice famliy but man everytime he got on the soundboard I was tempted to just unplug and sit there because I knew I would be turned almost off.
