Slumber is a melodeath/gothic doom combo based in Sweden and formed in 2002. Actually, I'm not sure if they're quite doom enough to go here instead of the gothic subforum, so I'll let someone more knowledgeable about doom make that call. Aaaanyways...

The combination of two of my favorite metal subgenres makes this something of an auto-win for me. They've only got one album to date in their catalog, 2004's "Fallout."
