If someone would have told me there was a group of people that are mostly City fans and have some big DBT/Isbell fans, I would have said no friggen' way, that can't exist.
One reason I say this is because these groups still mostly play some of the smaller venues in the US, not that I'm complaining there, as those shows are by far better than arenas or larger outdoor venues (RHCP, Foo, KOL, etc.).
So glad I was wrong or didn't take any such bet! Other musical groups haven't surprised me, but this by far has. Y'all rock!
