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?

Anything by Genesis after Hackett and Gabriel departed, and anything after Waters 'Mr Floyd' left Pink Floyd. Still haunts me after all these years.
Leonard Cohen's "Hallelujah" by J. J. Cale or Jeff Buckley or the original 15 verse composition by Cohen himself which I heard hom perform once.
Two songs on the John Hartford tribute album, done just before his death, are definitely haunting. Gillian Welch's version of "Tall Buildings" and John Cowan's version of Merle Travis's "Dark as a Dungeon".
I spoke of this song in a different thread...on the Stereophile Test CD 2 (from '92): track no. 7, "Ave Maria" - the famous Schubert piece performed flawlessly by a solo violinist accompanied by a chamber organ - recorded by Stereophile in a church on the highest caliber equipment. It is a haunting and beautiful performance. Truly moving.
