How big is the jazz band? If you have a small jazz band, that's fine. If you have a big band, you need someone to organize logistics. Somebody to book events. And if you're trying to make a profit, you might even need to adapt your style or respond to customer needs, such as a particular attire for different events. You might even have someone in that particular role. If there is a tour, it might even be a full time role.
