I recently got into Peste Noire, a French black metal band. One of their best songs, “Dueil Angoisseus,” has a short piece at the end that serves as an outro. I’ve read some comments saying that the band didn’t write this song, but that it’s an old church hymn from the ’90s. I don’t know how true that is, but I find the song at the end really beautiful, especially considering how chaotic the rest of the song is. If you could help me find it, you’d make my day. And please excuse my poor English—it’s not my first language.

if you wanna hear it here i leave a link, the song im searching begins in the minute 6:00
