It took me a while to find this one on Discogs, as you can imagine. For those of you that cannot read what looks Cyrillic: it says Georgian folk songs. In fact, the title is in both Georgian and Russian. The wonders of Google translate never cease to amaze me.
The style of singing presented here is Georgian polyphony, and was recognised as Masterpiece of the Oral and Intangible Heritage of Humanity by UNESCO in 2001. It is very different from what we are used to in the West: using a low pitched drone voice, with middle and high registers hovering over it, in a polyphony that uses close dissonances (seconds and fourths, that are considered dissonant in Western classical music).
The originals for this record were probably 78’s shellac records. It is a pity, because it means this is a mono record. It also means that these are as original as they come, before the tradition was touched by the taint of overproduction. These really are raw voices, and among the first of their kind. It was only in the late 19th century people started to write the songs down, and recordings like this are from the first decade of the next century.
