The original song is by an amazing band named Nightwish - if you haven't heard their music, then you definitely should look 'em up. It's kinda like Evanesence, but a little harder. =) Also can be compared to Lacuna Coil.
I already posted 'The Mission' by this band - Van Canto - no instruments except for drums. Everyone else just uses their voice. I <3 them.
