I like listening to Garrison Keilor until he goes off on politics. About choral music, he said this.
"To sing like this, in the company of other souls, and to make those consonants slip out so easily and in unison, and to make those chords so rich that they bring tears to your eyes. This is transcendence. This is the power that choral singing has that other music can only dream of." --Garrison Keillor
Hat tip to Dr. Dick.
