Metallica did not exactly have a great Grammys experience during their performance with Lady Gaga.
Metallica fans weren't happy with the Grammys this year. After losing the Best Rock Song award, Metallica was primed and ready to perform a big duet with Gaga when things continued to go wrong. Laverne Cox introduced the performance but only announced "Lady Gaga," failing to mention Metallica at all.
Then, Metallica lead vocalist James Hetfield's microphone wasn't working for at least 20 seconds of the performance, while Gaga's was working just fine. Hetfield moved over to sing into Gaga's mic with her until his mic was fixed. Hetfield was visibly angry about the mishap, throwing his guitar after it was finished.
Cox took to Twitter to apologize to Metallica and their fans for not properly introducing them.

Neither Metallica nor Gaga has posted on social media about the mic mishap, though they did post photos of each other:
