Now I know I've already posted a topic about metal but doom metal just kicks so much ass it needs to have its own thread. If you don't know what doom metal iis, it is basically metal slowed down. Check out www.doom-metal.com for a long list of doom metal bands, also available to search by sub-genre. Some bands that everybody should know are: Funeral, Shape Of Despair, My Dying Bride, Trouble, Skepticism. It's a great sub-genre of metal.
