Great thread, guys! There are some real gems here. Most of what I'd say has already been covered (especially the drummer hitting while setting up mics bit) but I'll try to add a few:
1) Guitar players who get stoned while arranging tempo maps with me, then wait until after the drums have been tracked to bitch about a missing eighth note at the end of their fill.
Them: "It doesn't fit anymore!"
Me: "Why didn't you bring this up when we laid down the tempo maps?"
Them: Silence.
2) People who don't flush. For fuck's sake, I'm an audio engineer, not a sanitation engineer, you fucking cunt! Pull the fucking lever, moron!
3) Musicians who don't know their parts. There's a difference between trying for an 'inspired improvisation' and 'not knowing the fucking song.' If you haven't learned the material, why the fuck are you in the studio? Does it not make sense to capture something amazing, rather than blunder your way through a session?
4) Girlfriends/hangers on. There's a reason there is no big, comfy couch in my studio & only limited seating. If you're a girlfriend/useless person, you're spending the day sitting on the floor. (they never, EVER, come back after that.
)
5) Drummers who can't be bothered to measure their tom sizes & give me false info so I buy the wrong size skins & we're screwed on tracking day.
.....I could probably write a doctorate thesis on the subject of drummers and how they should be stomped out of existence in the known universe, but that's for another thread.
