Oh my god, yes! This is my favorite song. So beautiful, gloomy, and enchanting. Sacro Culto is a wonderful album.
This is different from the one on Sacro Culto. I think this is the one that appeared on the Female Voices in Extreme Metal Compilation. It's much shorter, and sounds a little different...in production (?) than the Sacro Culto version. If this version doesn't blow you away, listen to the Sacro Culto version. It's missing the "Bathym Belem Gomor" chant, but perfect otherwise.
