Metallica’s drummer performed with his compatriots at their show at Telia Parken in Copenhagen on Saturday August 26th. Lars wasn’t the only surprise as the band invited on stage Mile Petroza (Kreator), Barney Greenway (Napalm Death) and Danko Jones. Ulrich joined Volbeat for “Guitar Gangsters & Cadillac Blood” as you can watch on the video below, but they also played another one. Watch the video to discover which was it.
