No, when I was there all seats were reserved
No. For most shows, there is reserved seating and non-reserved standing. (I assume there is disability seating, but that is also likely reserved.)
Seems to depend on ticket sales. They covered the floor with chairs at the Courtney Barnett/Kurt Vile concert which apparently sold somewhere between 2 and 3K tix in a space that could hold up to 6K. So GA turned out to be seated. I guess you can know in advance that won’t happen (i.e. sold out show). I’d love to know (day of) when it will. That would definitely increase my impulse concert ticket buying!
