The female voice: Diane Damrau, O zittre nicht (Oh don't tremble)
Starting at 3:49. 4:20+ is incredible and when she throws her arms into the air at 4:38 and the perfect notes at 4:48, amazing. What acting, what a voice! Gorgeous!
Edit: BTW, my mother told me that this was my father's (may he rest in piece) favourite piece of organ music which put it into a special place of my heart.
I've had an unusually busy year IRL so I suck at giving feedback (or just posting in general) but I do listen to what you're sharing, Krischy. I love classical music.
