Watch James Hetfield, of Metallica, throw a tantrum at the Grammy Awards last night (Sun. Feb 12th).
He was just coming off a steaming hot seat with Lady Gaga who shared the mic with Metallica.
Unfortunately, Hetfield’s mic was malfunctioning and his vocal parts were inaudible.
He later joined Lady Gaga at center-stage and the two shared the mic.
Watch his displeasure on display as the set wrapped up; taking it out on his mic stand and then tossing his guitar into the backstage area.
