The Mystery of the Bulgarian Voices Female Vocal Choir known in the past as The Bulgarian State Television Female Vocal Choir is an ensemble of rare artistic gift and enormous popular appeal. The choir truly represents one of the most amazing success stories in music. Created in the early 1950’s the choir’s first mission was to record authentic and arranged for multiple voices choral folk songs to be recorded and broadcast first on the radio and later on TV.
The Swiss music producer Marcel Cellier discovered the beauty of the Bulgarian folk songs, folk singers, their unique voices and choral skills and in 1975 released his first album with songs performed by the choir – 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 he released Volume II which in 1990 was awarded a Grammy Award for Best Traditional Folk Recording. It was at that time that the choir adopted the name “Le Mystere des Voix Bulgares”.
