Another Update:

Here's an Email I received from the sound people...

The ELECTRICAL
requirements for sound are as follows: #1 at the front of house
mixing tent, one 20 amp circuit,{ I could get by with 15 amps there if
you're short of amps elsewhere} #2 at the main stage I need two circuits
,one 30 amp for front of house system and one 20 amp circuit for the on
stage monitor system. IMPORTANT !!!! ALL THREE CIRCUITS SHOULD DRAW FROM
THE SAME BUSS BAR as well as the circuits for instruments on stage and be
PROPERLY PHASED so as to avoid ground loops . ALL LIGHTING AND CONCESSION
POWER SHOULD DRAW FROM THE OTHER BUSS SO AS TO AVOID SYSTEM NOISE FROM THE
LIGHTING DIMMERS AND VOLTAGE DROPS FROM OVENS,REFRIGERATION ETC. FOLLOWING
THESE RECOMMENDATIONS SHOULD INSURE A CLEAN SOUND FREE FROM VOLTAGE SPIKES
OR DROPS DUE TO LOAD CHANGES FROM THOSE OTHER SOURCES. I look forward
to working together to produce a successful show. KARA SWEETWATER

Wow... I'm not used to such straight forward, intelligent answers like this...

Great idea on splitting the loads by Buss too... How come you guys didn't think of that? (You probably did, but assumed I knew it too being as I'm the big musician / electrician and all?) [Linked Image]
