Hi Gregg, you probably have heard or thought of these ideas, before. However, review is often helpful:
Be sure to A/B reference material at the monitor gain position you're working at (or at least attenuated in calibration to that level).
Don't forget to watch how much time is spent talking. Try not to debate politics or philosophize Nietzsche or proselytize sinners or anything nut-ball like that, while on the clock.
The client is not always right. Don't be persuaded to deviate from your work-flow until you have thought it through. A good idea from a lay-person may be inspired - or, quite possibly, it may only be reasonable on the surface. What Cass said is quite right. You are the ME - it's your room. Don't let the tail wag the dog. They want your advice. Don't take theirs with anything but a grain of salt.
If it sounds good, it is.
Only hard-bypassed bands don't interact.
Green tea, o kudasai.
Do bathe. Seems unnecessary, but you might wish you had done so... Especially if Nasui (or Quincy Jones) comes over during the session.
Having a friend come over to rescue you at around the time you think your session will be over, in case it's a setup, is probably wise - especially if it's the first time you meet with dude. If you can phone your friend with an innocent-sounding statement, such as, "Red Licorice," you can agree ahead of time that that means, "SOS!," or similar. With all that nice equipment, if you don't have security guards, or at least a secretary, you could be a sitting duck for robbery.
Viva la unattended session.
Good luck,
Andrew
(P. S., I listened to the other songs in the Peppermint Waves collection. My favorites are still the first three tracks. Somehow, compositionally, I was less entertained by the others. The mastering was fine, however. Most of the value of a song is the performace. Second is the composition. Third, the mix. Last, and least, the mastering. So, enjoy the low pressure mystery tour, Gregg J.!
