Here is a traditional song on the Biblical Psalm XXII ("My God, My God, why have you forsaken me?"), arranged and sung by the great singer Magdalith.
Magdalith is a renowned French singer of Jewish and Gregorian songs with a voice covering three octaves and she has made several records. She has made an enormous work of rediscovery of the Gregorian song and several religious communities in France and abroad use her songs for their liturgy (she sticks to the theory that the Gregorian song originates in the songs of the synagogues). She is also a composer and has recorded some experimental compositions of her own, where she sounds a little like Yma Sumac, backed by minimal percussion, occasional keyboards and xylophone. Magdalith says of herself: "I am a dancer on the vocal cords".
Listen to her deep contralto voice and enjoy!
