I lucked into free tickets at the B&S show at DAR in 2010, so I don't know what they cost (but DAR tix are rarely economical in my experience) and it was absolutely worth $50.
LOVED LOVED LOVED the 2010 DAR show
Trying not to complain too hard. I do remember paying roughly $50 for the Echostage show in 2015.
I'll probably cave and buy a ticket because it's worth it. Would love to see them in CDMX, that's for sure.
