Oh heavens! You mean that people can somehow get enough cues from the recording that they can get a sense of the size of the venue and its ambience? It’s all a trick I tell you! Those damn recording engineers put that crap in there! It’s not real I tell you! It’s a figment of your imagination and all of your friends that heard it. At least that is what someone on this forum has tried to convince us of.
Seriously, I would love to hear the tape.
I may have missed that thread. Verticality is a challenge for conventional stereo, but breadth and sense of distance from the listener are a cinch, particularly when done this well. There's actually a nice bit of text on the cardboard cover of the recording explaining the recording engineer's challenge, as Belafonte was wandering all over the stage, and was singing with a number of different ensembles, from small intimate orchestra to the entire hall joining in. The sum creates a wonderful sense of space.
Was very lucky with my copy of Belafonte/Carnegie. Unused until it reached me!
