Re: what do your band mates do as a job.
The 50 hz / 60 hz becomes annoying in my field, post-production for film/television. Where N. American audiences watch standard def. TV at 30 frames / second and folks on the other side of the pond watch at 25 fps. If it's filmed on actual film, it's captured at 23.98 frames a second... convert that all into something that can be seen on both sides of the ocean and your head starts to spin. More so when the show needs to be an exact duration...
