Following a much-discussed, glitch-ridden performance with Metallica at this year?s Grammys, Lady Gaga posted a video of how the performance was supposed to go.
The video, posted on Lady Gaga?s Vevo channel Friday, shows Gaga, James Hetfield, Kirk Hammett and crew tearing through ?Moth Into Flames? during a dress rehearsal for the awards show. The Grammys performance was marred by glitches that Metallica attributed to a dead microphone.
