You knew it was gonna be a rough night for rock and metal music at this year's Grammys when Megadeth won Best Metal Performance and Metallica's "Master Of Puppets" played as they accepted the award.
Then when it came time to introduce Metallica, Laverne Cox "forgot" to mention Metallica by name, instead introducing ONLY Lady Gaga (Cox has since tweeted an apology).
The icing on the crap-cake was James Hetfield's microphone. A stagehand apparently unplugged it accidentally.
I'll give Metallica credit - they fought through all of it but afterwards Hetfield couldn't hide his anger... tossing his guitar and whipping his pick back towards his guitar tech.
