I will say this: Once the lockdowns end we will see a LOT of pent up demand explode.
Actually unless concert promoters and venues start canceling shows, refunding tickets, and starting with a fresh calendar, the dates are going to be booked up for at least a year in advance.
I have tickets for 2 different concerts that have been twice postponed. These tours are still “on” and will be going around the world.
Now take 1 year+ worth of tours that have to be rescheduled (the Who were already rescheduling 2019 concerts from Roger’s vocal problem). If you don’t already have an agreement with a venue/agency you may find it hard to get a new tour or concert off the ground.
