It's been a few weeks, but we bet no one's forgotten about the unfortunate mishaps that occurred during Metallica and Lady Gaga's fiery Grammys performance.

However, Metallica have posted a video from the Grammys dress rehearsal, which saw “all cylinders firing just right.” See what the performance should have looked like below.

Soon after the performance, Grammy Awards producer Ken Ehrlich issued an apology to Metallica, saying, “My guys' theory was that … one of the extras [on stage] accidentally kicked out the cable that went to the mic.”

During the performance, singer James Hetfield's mic didn't make any sound, so he shared with Lady Gaga.

Metallica's statement before the video:

“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 a week ago … hmm, would that qualify as an understatement?!? For those of you who missed it, we’ve posted the live broadcast version here.

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!”

Metallica will be joined by Avenged Sevenfold, Volbeat and Gojira for a massive U.S. tour starting in May where they'll be performing songs from their latest album, Hardwired…To Self Destruct, as well as classics.
