Last night’s Grammys Awards ceremony featured a tribute to Ozzy Osbourne , who passed away last year at the age of 76. Post Malone , Duff McKagan, Slash , Chad Smith , and Andrew Watt teamed up for a faithful rendition of Black Sabbath ’s “War Pigs,” the band’s rousing anti-war protest song from 1970, while balls of fire exploded behind them. Watch the performance below. As the group of musicians tore through the metal song, an image of Osbourne with his arms outstretched was displayed onscreen
