This is some gooooood stuff. Metallica in the tuning room prior to their show in Pittsburgh in October 2018, working out some kinks. Go ahead to 7:30 in the video when Lars suggest they play "Deliverin' The Goods" by Judas Priest to help them loosen up a bit. I didn't expect that he'd sing, but he sure does. Safe to say that James is in no danger of being replaced by Lars on vocals any time soon.
