The best one-song album/EP!

You know I haven't actually heard any of those. If it's allowed, I'll say Other - Transatlantic - The Whirlwind. Not metal, and broken up into 12 tracks on CD, but is is one song.

Sabbat - The Dwelling

Of course I'm voting the Dwelling.

Quite right, but still a good one. Here is another one instead of it (a live instrumental monster track album):

Asva - Live In London

There's many, many one track albums out there.

If not in this poll, (or on this site) Ictus - Imperivm is a crust punk/heavy metal epic at 39 minutes.
Nitberg's Nagelreid is 56 minutes of (NS) black metal.
Hypothermia's Skogens Hj�rta is a 68 minute "black metal" instrumental which mostly borders on post rock.
Wyrd's Heathen at 51 minutes
Darkestrah Epos at 33 minutes.
A new one: Ysengrin To Endotation at 40 minutes.
Gravetemple also released a really low print run of 350 copies of Le Vampire De Paris at 54 minutes.
