Disappointed watching Metallica's off mic performance with Lady Gaga of "Moth Into Flame" at this year's Grammy's? 

Metallica have decided to share a video of the dress rehearsal when all things technical went to plan.

Metallica said "Perhaps you've heard by now that we experienced a slight bit of a technical difficulty when we hit the stage at the Grammy Awards with Lady Gaga a little over two weeks ago. We've had so many of you ask and wonder 'what if,' so we thought it might be fun to also share with you what happened just a few hours earlier that day at the dress rehearsal with all cylinders firing just right. Collaborating, hanging and performing with Gaga was easily one of the most exciting, inspiring and enjoyable experiences of our career — she BRINGS IT every single time!! All we have to say is that we absolutely cannot wait until next time!"
