Demza 5: There must be an angel The Bulgarian State Television Female Vocal Choir throw down some angelic harmonies for your delectation on day five of the Giftravaganza. Never fails to stop me in my tracks.→[More:] The song is a love chant, available on the first Mysteres Voix Bulgares album. An incarnation of the choir was on tour at the end of this year, so they might be getting about next year as well. Worth it for the outfits alone!
