an Entity references as follows:
A tour manager (or concert tour manager) is the person who helps to organize the administration for a schedule of appearances of a musical group (band) or artist at a sequence of venues (a concert tour). In general, road managers handle tour details for their specific band, while tour managers are used to oversee the logistics, finances and communications for tours as a holistic entity. So, on any given tour, you may have road managers taking care of each band as well as a Tour Manager responsible for caring for the entire tour. Very often, the Tour Manager is also the headlining band's road manager.
