The most haunting music you ever heard?


I listened to the acoustic version of "Under the Milky Way" from the band "The Church". I can only describe it as haunting. Jokes aside, which might be too much to ask :-), what is the most haunting music/song or cd you have heard?

A track on the Mulholland Drive soundtrack is chilling. It's a spanish a cappella version of Roy Orbison's Crying titled Llorando by Rebekah Del Rio. Crazy deep & cavernous reverb and what a voice.
I would say the first movement to the Rachmanioff piano con no#3.....stunning music. The 3rd movement to the Sibelius sym no#2....
The second movement of Chopin's piano concerto #2, especially when played by Charles Rosen, it virtually shimmers as it disapears
