Metallica doesn't exactly hide the fact that they're fans of Ghost. Lars Ulrich has been caught air drumming to the band before and Kirk Hammet was recently featured in Ghost's unveil of their new song "Dance Macabre." Now James Hetfield has posted footage of himself online jamming to Ghost's 2015 single "Cirice" at Metallica HQ, where bassist Robert Trujillo also joins in.
If we can just get all four of these dudes to play the song at once, I bet Hetfield could do a pretty gnarly impression of Papa Emeritus.
