What's the most stressful, highest stakes, pressure inducing job in audio?
My guess:
Grammy awardee music playback engineer. This cat has to listen to the person at the podium in the Staples Center read off the winner's name and has to instantly with no delay start the playback of that artist's song that won. If you slip or hit the wrong track - ouch. Oh, and by the way, they keep the winners confidential until they are read from those little envelopes, so no rehearsal or list of awardees for you. No pressure!
"The winner is... Taylor Swift!!"
PA: "We gonna sip bacardi like its ya birfday..."
