If you haven't been amazed yet today, then you're about to be. A woman at a recent classical concert in Zurich launched into a rendition of Metallica's 'Master of Puppets' - on a piano. Watch as she will completely blow you away with her cover of one of the greatest metal songs of our time. I never knew fingers could move that fast on a piano. Incredible.

As if this isn't enough metal piano for you, the woman, who goes by the name vkgoeswild on her YouTube channel, mixes up a version of Metallica's 'Battery' and Slayer's 'Raining Blood'.

Man, this chick knows how to rock the piano.
