Mostly events in Brazil happen in Sao Paulo or Rio, it's rare to see mainstream artists going to other places. Many people will travel 1.000 miles or more inside Brazil to see LP in these concerts right now.
I hope they sell out or at least close to it today, cause if they don't i don't know if they will come back again to southern cities like Curitiba or Porto Alegre (they went there in 2012).
Last year they announced a Porto Alegre show for this 2025 leg and it was supposed to be in a BIG stadium. 50k+ capacity. And it was cancelled a few months ago.
The 2012 Curitiba concert had already tickets sold and they changed venues due to low demand, most people that would watch the Curitiba one decided to go to Porto Alegre. And the Porto Alegre venue had already been reduced from a 25.000 capacity to 15.000 capacity, also due to low demand.
Curitiba is one of the best Brazilian cities. Well developed, feels like a European city, very cultural and artistic, low crime rates (way lower than Rio/SP)
