I couldn’t make it to the show, so I’ve just enjoyed watching the many youtube videos posted covering the show. I watch them in my home theater on the big projection screen with a good surround system (Hales Transcendence speakers)
and the impression of "walking in to those rooms and hearing the sound" can be almost eerie. Even if, of course, it's hardly fully accurate to the real sound, there is nonetheless a sense of the sound changing quite specifically from room to room.
In any case, I’ve certainly had my yearly fill of "single female vocalists with sparse instrumental accompaniment." Gag me with a spoon.
