Lady Gaga and Metallica took the stage together at the 2017 Grammys tonight (Feb. 12), delivering a dynamic performance of Metallica's 2016 single "Moth Into Flame," despite a technical error that left James Hetfield's mic mostly silent.

Hosted by James Corden, the 59th annual Grammy Awards ceremony took place at the Staples Center in Los Angeles on Sunday, February 12, broadcast live on CBS. The 2017 Grammy Awards nominees were announced on December 6, with a tribute performance to Prince.
