It’s become somewhat of a tradition for Down to be joined onstage by fellow musicians to jam on “Bury Me In Smoke.” And during the Copenhell festival in Copenhagen, Denmark this past weekend, Down were joined by Gene Hoglan and members of Testament for such a jam. Hoglan was kind enough to post drum cam footage of his guest appearance online. While you can’t really see or hear the other members of Testament or Down onstage, we personally could watch video of the Atomic Clock drumming for hours. So watch for yourself above.
