Mastodon

Voted 2004's Album of the Year in Kerrang!, Terrorizer and Revolver magazines, Leviathan is a concept album based on Herman Melville's Moby Dick. The Atlanta prog-metal band's critically acclaimed combination of sludge-metal punch and Thin Lizzy-harmonized guitar leads made just about every metal fan in America say "UHG2BFKM!" when the album appeared and promptly began embarrassing everyone else in '04. Its only failing is that you can't actually toss harpoons at sperm whales while listening to "Seabeast."
