About Le Mystère des Voix Bulgares:The famous Bulgarian women's choir Le Mystère des Voix Bulgares ('Mystery of the Bulgarian Voices') is comprised of 22 members. Performing in traditional clothing, the varying voices of the choir weave together in a serene manner, forming cunningly complex arrangements. The ensemble originated in 1952 (as The Bulgarian State Television Female Vocal Choir), and has since been performing ancient Bulgarian folk songs which, thanks to the innovative vocal use, conjure melodies that take you across time and space.
