Yeah I remember reading an article on AJ and Soundwave. These types of people are king's amongst men.No worries, I've worked with a few promotors in the past, providing legal contractual advice and for what they do and the risks they undertake, most of them are paid a pittance and without insurance, some simply couldn't exist.
Huge amounts of day/hours, coordinating and managing checklists into checklist details and then the artist arrives and says; 'don't like the lighting, the stage is too high, get rid of the first 10 rows of seats, why isn't there fresh fruit in my green room?' etc. etc.
My older sister saw Donna Summer live in the early 80's and claimed then and for years later, Summer was the best live singer she had ever heard..?
