I've heard of the Swans before, though I can't remember the context; mayhaps in my time as Music Director in my college radio station.
At any rate: His voice is so incredibly haunting, reminiscent of Nick Cave or Leonard Cohen (with a twinge of Stephen Merrit). The song is melancholic. I like it. I'm going to have to add the Swans on my list to explore. Good pick, Step.
The immediate connotation being Leonard Cohen, I thought of
His version of Hallelujah
and
Everybody Knows
I can't pick just one right now.
