Last year, Post Malone proved to a lot of people that when it comes to playing rock music, he knows what he’s doing. His Nirvana tribute set was one of the year’s finest livestream concerts, and he brought a similar energy to his New Year’s Eve show last night.

Malone’s “Bud Light Seltzer Sessions Presents New Year’s Eve 2021” performance was mostly original songs, but he brought hard rock to his two-song encore. Joined by a band that included Red Hot Chili Peppers drummer Chad Smith, he ran through Alice In Chains’ Rooster, putting on his best post-grunge snarl. Slash then joined Posty for a cover of Black Sabbath’s classic War Pigs, which they stretched out to ten minutes and absolutely rocked.

The live stream concert also featured appearances from Jack Harlow, Steve Aoki and Saweetie, kicking 2021 off to a rapturous start.

Watch Post Malone's set from 1 hour and 36 mins to 2 hours and 27 mins, with the Black Sabbath and Alice In Chains covers starting around 2 hours and 11 mins.
