It's been four years since Lemmy passed away, and a group of his biggest fans and brothers in heavy metal are revisiting one of their hardest-rocking moments onstage with their friend and hero.

The Mötörhead bassist and frontman, born Ian Fraser Kilmister, died on Dec. 28, 2015 following a brief and brutal battle with cancer. He was both an inspiration and collaborator of Metallica's: they wrote "Murder One" off 2016's Hardwired… To Self-Destruct as a tribute to Lemmy and have covered Mötörhead cuts in the past, and had joined him onstage in 2009 to roar through "Damage Case" and "Too Late."

Metallica shared footage of this performance on Saturday (Dec. 28) to mark the anniversary of his passing, and their adoration of Lemmy is fully present and accounted for in the clip. James Hetfield and Kirk Hammett's joy is apparent in the broad grins plastered on their faces for the duration of their 9-minute spell with Lemmy, and Robert Trujillo playfully engages in a bass-off at one point.
