The most haunting music you ever heard?

James Taylor singing "Overcoat" on Jerry Douglas' "Look Out For Hope" is both sad and haunting.

Dory Previn (anybody remember her?) "Doppleganger" This one really gave me the willies every time a buddy played it during my college "daze"

I think "Yulunga" from Dead Can Dance "Into the Labyrinth" fits this category too.

One of my neighbors was playing some spooky music on their porch for halloween.

Grace by Jeff Buckley.

Johnny Cash- American V - deserves a mention.

I remember Dory Previn. A couple of years ago I sold most of my lps. Some were harder to part with than others and "Mythical Kings and Iguanas" was a sentimental favorite that was really hard to let go.
