Live production people tend to treat house of worship work as the shallow end. I have run both ends of it and the assumption does not hold up.
For 4 years I ran a performing arts center near Boston. 3 shows a week in the off season, 9 a week in the summer, at or above 200 a year. The acts arrived with the show already built. Rider, input list, sometimes their own engineer at the desk, sometimes me mixing the show myself. We supplied the room, the system, and a crew that could receive whatever came through the door and put it in front of an audience that night. We were good at it. And the show existed before it reached us.
I mix at a church in Houston now. Sunday looks like this.
5:30 AM setup.
7:30 rehearsal in the chapel.
8:30 to 9:45 first service.
9:45 second rehearsal, in the worship center this time.
10:45 to 12:15 second service.
Teardown by 12:45.
Almost nothing carries between the two. Different musicians, different music, different room, 2 separate AV systems. Whatever I built for the first service is worth nothing when the second one starts. The worship center band rehearses Wednesday night. The chapel musicians’ only time on the system is 45 minutes on Sunday morning. Both services go out for broadcast, a second mix with its own requirements, and I am carrying 4 to 8 IEM mixes alongside the house and broadcast mixes the whole way.
A touring act plays a show that was designed, rehearsed, and documented once.
Most of the people doing this work do something else for a living.
The show that arrives finished is the easy one.
