The first time I ever heard Metallica was back in the 80's, I was 6 years old at my buddy Eric's house, his older brother had a boom-box cranking "One" and I remember being totally freaked out by the sound coming out of those speakers.  I was probably going to hell now... great. Thanks Eric's older brother...

If you'd told us that in the year 2014 Metallica would be on the Grammys with classical pianist Lang Lang, we would have never believed you.  But it happened. Last night.  Here's the performance, obviously dubbed from another countries broadcast, for you to check out.
