It's a common thing with sound guys. Not all, but many.
They think you, the musician, are there to serve them. They don't get that their PA systems are supposed to provide sonic support for the band. You'll hear comments like "too many players think it's still Woodstock, they don't understand the requirements of modern audio" and other BS.
I've known quite a few good sound guys in my time. They accomodate the band and still manage to get a good monitor mix AND good FOH mix. They are the ones who truly know their craft. Wish more were like that.
"We don't use AKGs here so you'll have to move the block"??? ROFL! What a loser.
I used to think I was Libertarian. Until I saw their platform; now I know I'm no more Libertarian than I am RepubliCrat or neoCON or Liberal or Socialist.
This ain't no track meet; this is football.
