Day 28: A song by an artist whose voice you love:
Bill Leeb, Front Line Assembly

I'm not a vocal person. That's part of the reason I can listen to death metal music.
Sure I love the heck out of well-produced vocal harmonies, but that's not necessarily the same as listening to one vocalist consistently (Sorry Spock's Beard and Gentle Giant).
