Most achingly-beautiful music

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.

My recent find IDM " The kilimanjaro Darkjazz Ensemble"
Modern Jazz sound form Nostalgia 77's " The Garden" and " Songs for my Funeral"

Procession of the nobles by Rimsky Korsakov

Dinner and Nocturn. Soundtrack to the Lady Caliph. Ennio Morricone, played by Yo-Yo Ma.
Silent Lucidity. Queensryche.
Love Theme. Soundtrack to Bladerunner. Vangelis.

Although I mostly listen to classical music, it is hard to beat Eva Cassidy's later recordings - particularly the album "Live at Blues Alley" when she already knew that she was dying (from melanoma).
