Shavnabada - For Learning: Georgian Church Chant: Hymns of the Baptism, Ordination of Priests & Holy Matrimony (2014, Georgian Patriarchy Church Chant Center)
This 2-disc collection of church chants in traditional Georgian polyphonic style has an interesting conceit: each of the eleven songs on the album is presented four times in a row, first as a normal recording and then one time for each of the distinct vocal parts, with the respective vocals elevated in the mix so you can more easily follow along as you learn. I haven’t tried (and I can’t be bothered to scan the booklet of sheet music included in the CD case, so good luck), but it does also make for interesting listening.
