Having fronted a Nirvana reunion last year (and before that, an all-Nirvana covers livestream with Travis Barker on drums during Covid lockdown), Post Malone continued his covers career at the 2026 Grammys, where he fronted an all-star Black Sabbath tribute band, in honor of the late Ozzy Osbourne. Post has collaborated with Ozzy, and his bandmates — Andrew Watt, Red Hot Chili Peppers’ Chad Smith, and Guns N’ Roses’ Duff McKagan and Slash all had as well. They performed Sabbath’s iconic “War Pigs” as the Grammy’s “In Memoriam” segment continued behind them. Watch a clip below.

Also visible during the performance were Ozzy’s widow Sharon, and their children Kelly and Jack, watching in tears from the crowd.
