Came here to say this after finding a video of them performing it during an encore (it's not hard to find). The first half of it especially blows me away and to be honest it's some of the most gorgeous brass writing I've ever heard. I, too, would love some potential info on when it'll be in. Really hoping I'll get to see it this upcoming Monday at the AZ show - only show I can attend this season. At the very least catch them rehearsing it if they venture out into the Phoenix heat.
On that note, does anyone know how best I can go about finding them when they're in town?
