This is Marco Tapani Hietala, the bassplayer in the metal band Nightwish. Man, his hair is so cool. Combined with the beard, this looks so good that I might even try this myself sometime in the future. :)

He's probably my idol in terms of hair and beard epic-ness (if that's a word). But i'm not sure i'd want to look like that.
My favorite is Tuomas (also Nightwish):
