I see it too. The tricks of the trade that are tribal knowledge are being lost. Simple stuff, like turning the keyboard player to center if he has an open mike, using a sub-mix, etc., are things we rarely see anymore.

The result is bad sound, no separation of the instruments and all the other ills as a result of losing that expertise. Sometimes it seems that sound guys today just want to walk around the room with an iPad screwing with the mix and acting like they're part of the show.

Lighting, don't get me started. With all the new LED gizmonics you kind of get the feeling the lighting guy thinks the band is a necessary evil just so he can pretend he's at some underground rave.
