This second volume of Le Mystere des voix Bulgares features performances by the Bulgarian State Radio and Televison Female Choir and the Female Vocal Choir, Sofia. This dynamic music comes from an oral tradition. Though the true folk style is dying out, these songs are preserved in modern versions which combine folk with classical elements creating a new art form. Bulgarian vocal music is usually sung by women who are picked for the natural beauty of their voices. The performances on this CD were recorded in the 70's and 80's. "Ovdoviala Lissitchkatka" recorded in 1957, however, sounds closer to the original folk style than the more artfully arranged pieces. All of these pieces are truly fascinating. GRAMMYwinner in 1990.
