Metallica went on stage with Lady Gaga at the 58th Grammy Awards and they played Moth Into Flame, which song from Metallica’s last album “Hardwired… To Self-Destruct”. During this live show, Lady Gaga belted clearly into the microphone, but James Hetfield’s microphone wasn’t working.

Speaking in a recent interview by New York Post, James Hetfield spoke on his microphone problem at the 58th Grammy Awards. He said:

“I felt embarrassed. I haven’t been that angry in a long time. When something out of my control goes wrong, I still get wound up. I’m sure it taps into other stuff from my past, but I felt helpless.

I agree, it ended up being a blessing because I ended up singing in a microphone with Lady Gaga — maybe even more than she wanted. It felt more like a real collaboration because of that.”
