Veljo Tormis: "The Lost Geese" from "Litany to Thunder" - by Estonian Philharmonic Chamber Choir - 2 sopranos in conversation with piano accompaniment
"A Feather on the Breath of God" - compositions by Hildegard of Bingen - sung by Emma Kirkby and Gothic Voices
"Zaide" the piece Arie Ruhne Sanft - my favourite is Sandrine Piau on her CD "Mozart Opera Arias"
Irina Mikhailova's CD "Russian Twilight". Several amazing tracks that are painfully beautiful: Zarya, Zurahvo
"Lux Feminae" by Montserrat Figueras.
Achingly-beautiful music to me always involves the female voice - nothing else comes close - I enter Angelic Realms and long to leave this earthly realm.
