American heavy metal band Pantera has just sent a rare video through their social media account. In the video, the American rapper Post Malone, who sang with Ozzy Osbourne on his third studio album Hollywood’s Bleeding, is singing Pantera’s Walk, which is taken from the band’s sixth album Vulgar Display of Power.

Also, the band’s lead vocalist Philip Anselmo posted a photo with Post Malone and said, “New blood meets old blood… it was a real pleasure to meet Post Malone, genuine & genuinely nice kid. The nieces & nephews are definitely jealous.”

Watch that rare video below.
