When I was in high school, I was involved in our Chorus as a Tenor/Baritone.
One event we performed was a chorale competition at another school where a half dozen or so schools go to show off their chops.
We warmed up performing Carl Orff's Carmina Burana. In a library.
I was near the middle of our group, completely immersed in the sounds.
Live, loud, zero distortion vocals in a room that was pretty dead acoustically.
It was truly spine-tingling!
It is that "chill running up and down the spine" sensation I'm still chasing.
I have experienced it:
First in a stereo store mid-1980's with a McIntosh component rack driving a set of Klipschorns.
There have been several others.
Occasionally, with the right source material, my KG-16's will do it too.
