Ghost and Metallica were recently tourmates over in Europe, and clearly they've become friends. Or at least Ghost vocalist Tobias Forge and Metallica guitarist Kirk Hammett have become friends. You can watch the two bond over talking about weird guitars, being on tour, preparing for tour, and what it's like to be out on the road a whole low.
Frankly, the video is a lot of fun, especially because Hammett seems so into it.
