Not every person in the music and concert promotion industry is important to you as a photographer. It's therefore good to know who's who in the household of an artist. Let's start at the top of the ladder with the artist himself.
The artist, in an artistic and creative way, is the absolute boss. If you are in close contact with the artist, anything can be arranged for you. His wish is everyone's command.
The manager has more or less the same status as the artist. His responsibility concerns the exploitation of the artist—from strategy to performance, recording contracts, concerts, finance, tickets, merchandising, food and beverage turnover, you name it. A good contact with the manager can give you unlimited access.
