We've come a long way from the days when rock 'n' roll dominated the Grammy Awards. But fans of the genre still have plenty to look forward to at this year's ceremony.
It was set to be an interesting pairing for Grammy perfromances: Metallica & Lady Gaga. They took the stage and Lady Gaga looked the rocker part. However, someone forgot to turn on James Hetfield's mic. He eventually realizes something isn't right, and share's Lady Gaga's mic to save the perfomance.
