Metallica were joined by Lady Gaga tonight at the 59th Annual Grammy Awards to perform “Moth To Flame” but trouble struck right from the start.

Unfortunately, singer James Hetfield's mic was producing no sound for most of the performance. As they say, the show must go on, so Hetfield shared a mic with Gaga for the majority of the show. Despite the technical difficulty, they put on an explosive performance.

Metallica's “Hardwired” was nominated for Best Rock Song but lost out to David Bowie's “Blackstar.”

Metallica and Lady Gaga have 35 total nominations between them—18 for the band and 17 for the singer.
