Nice singing (of course) but it seems like a bit of a missed opportunity, production-wise, in that they *could* have put together a video demonstrating the polychoral aspects, showing perhaps eight boxes of five singers during the tutti portions, enhanced with cutaways to interesting lines, etc. The did a little of the latter, but the editing was pretty random. I'm guessing that they didn't capture video of all of the sub-sessions, so they didn't have the option of doing this up on a scale of the Eric Whitacre YouTube productions.
