When you are a recording engineer, you deal with a lot of people who are firmly deluded into thinking they are good.  Those are the ones that give you the most trouble because you have to work 10 times as hard just to make them not sound as bad.

Then again, a very few times in your careered, you are blessed with people who are truly gifted in their craft and your job is to simply mike them up, set levels, press record and just sit back to admire the moment while thanking the higher being you believe in for the glorious chance of putting this much beauty on tape.
