Marcel Cellier, Swiss music producer, discovers the beauty of Bulgarian folk songs, folk singers, their unique voices and choral skills and in 1975 releases his first album – Volume I which he called “Le Mystere des Voix Bulgares”(The Mystery of the Bulgarian Voices). The album soon became a best seller. In 1987 was made Volume II which earned in 1990 to Marcel Cellier and this choir which is the main performer on the album, the American “Grammy Award”. It was at that time that the choir was called “Le Mystere des Voix Bulgares”.

They were originally called The Bulgarian State Television Female Vocal Choir (but in Bulgarian) up to that point.
