Pedestrian Gods
I heard one in a tiny church once and it felt like the room was splitting the voices up for me, which helped a lot.
Maybe that is the trick with these recordings too, not just the singers but the acoustics doing some of the sorting.
Yes, and the structure is what makes it stick with you. I still think the best examples are the ones where you can hear each voice working, not just a nice wall of sound.
Do you have a favorite recording where the separate parts stay really clear?
