Heavy, Power, Prog, Death, Doom, Black, Thrash. That's it for metal. Doom, Black, and Death are the only real obscure ones.

But not too obsucre. There is a band getting MTV/Rolling Stone mention called The Sword. They're obviously doom metal/stoner rock.

Back on topic: Listen to My Dying Bride. The albums "Turn Loose the Swans" and "Songs of Darkness, Words of Light" are what you're looking for.
