I think a lot of it also helps to be inside of. I had the good fortune for a few years around the turn of the century to sing in the Holy Name Cathedral choir in Chicago and the choir director programmed a lot of 20th-century classical work alongside the blue-haired lady standards and renaissance works. One of my favorite pieces had the choir singing a C chord while two sopranos sang a descant of Db-Ab above it. Aside from sounding really cool, it was also a really difficult feat technically speaking as those are not intervals that are easily sung. It was quite the education, although I started to realize as I worked on my own music that I was no longer hearing dissonances the way I used to.
