As of Monday, Rock’s Fox Theatre show in Atlanta July 29 was sold out. It’s unclear if it was already sold out before his Oscar appearance, but Stubhub has tickets starting at $94. By Monday afternoon, there were more than 300 tickets available on that site. Fox Theatre has a capacity of 4,665. (The cheaper seats by Wednesday morning were long gone, with the lowest priced ones going for $235 and the number available falling to 187.)
Regular ticket prices, if you had been lucky to get them when they went on sale, ranged from $49.50 to $135 before fees.
