Looks like a beautiful collection of ancient Mesopotamian poetry set to the original lyrics (relatively, of course) with close-to-original instruments.
I’ve always wondered what the Hymn to Nikkal (the world’s oldest song that we’ve recovered) might have sounded like.
Of course, we don’t really know what ancient Sumerian, Babylonian, Akkadian, or even Attic Greek really sounded like, but we do know that these languages were inherently more “musical” than English.
What did ancient Babylonian songs sound like? Something like this.
