You'll want good comments about you in the way you treat the artists and all. Seems like half the battle to stay on the gig is how well others like you as compared to how well you mix. It's been a long time since I heard a really good live mix these days. Sometimes I think the mixer guys have lost a lot of hearing in the 3K to 10K area. Most mixes are so harsh with high end it's hard for an older guy like me to listen to it.
Break a leg and stay cool.
