The production manager of a musical ensemble is in charge of the technical crew.
The technical crew moves independently of the band because the technical crew must arrive at the gig location by the morning of the show to start setting up the equipment.
As the tour is being planned, the Production Manager must contract for services such as lighting, sound, trucking, rigging, bussing, and catering.
Specific discussions must take place between the Production Manager and the providers clarifying the quality of the equipment, management and crew, as well as the prices bid.
At this point the tour manager takes over the leadership, as the technical success of the tour depends on the crew members working together effectively and efficiently.
