Colleague of mine - we'll call him The Cap'n - was Motorhead's front-of-house mixer for a while. We advanced them at the Catwalk; their tech rider specifies that the PA must be able to generate 120 dBC slow program at Front of House. We asked him if they were serious because, well, that's stupid numbers. The Cap'n assured us that if he couldn't produce that, he'd be fired - the tour manager wandered around during sound check with a sound level meter. We backlined a triple stack of EAW. I didn't get to see the show, can't remember why, but I remember it was dangerously loud.
Fast forward a couple years and The Cap'n is back mixing shit bands at one of the hole-in-the-wall clubs in Pioneer Square. What happened? Not loud enough? "ha ha" everybody laughs. I decided Lemmy was an asshole.
Fast forward another year and I discover that what really happened is The Cap'n decided to get Motorhead to invest in a $20k front-of-house console. Back of Pro Sound News endorsements, etc. Except The Cap'n was on vacation and the console had an issue, so the tour manager called the company and bitched about their piece-of-shit console.
"That's no way to talk to us after we gave you a free console," the manufacturer said.
Yeah. The Cap'n took an endorsement and told Motorhead they'd paid full price and pocketed the money.
I decided The Cap'n was an asshole.
