Rule #1 of commercial ticket sales:
Sell the worst seats first.
Give people the impression that all the good seats are selling out, and that they better buy their tickets soon, because before they know it, they'll all be gone.
As the performance date gets closer, better seats will be released, with the absolute best being sold on the day of the performance, usually two and a half to three hours prior to curtain. These are the released premium seats.
