A: Organising tours into Concert Series gives management more granular control over the supply of the tickets.

Being able to accurately meet demand in each city on tour is the difference of a well-managed tour and a flop. It makes all the difference. This is why we now see the biggest acts not putting their whole tour on sale right away – but gradually adding performance dates over a number of weeks. They're assessing the demand and providing the supply where and when appropriate.

Setting up a tour in the fitting venue size for the act makes a sold out tour more likely. When the demand increases, having the space to add second or third (or seventh) show and then doing it means that those who want to attend, can. This can diffuse a Twitter storm before it even gathers wind – and more importantly, kill the secondary ticket market. The fans love it.
