Post Malone jumped on stage with a band in Detroit, over the weekend, and belted out a version of 'Santeria' by Sublime...and it is epic!
The band Post jammed with is called Collison Six, and the party went down at Axis Lounge inside the MGM Grand in Detroit.
Its unclear if Malone planned on jumping in to do the song or just felt the vibe and jumped on stage, either way magic ensued.
In the video, besides the unbelievable version of the song, you can see the crowd is loving the impromptu show.
Also, PM has actually performed the song over the summer with 'Sublime With Rome,' with members of the original band.
'Santeria' is a classic hit by Sublime released in 1997.
The song was released after the death of the band's lead singer Bradley Nowell. But, the official video features members of the band and images of the singer in the sky.
The video also features the singer's dog, 'Lou.'
It's not the first time Post has jumped up to do something similar, we caught up with him at Paddy Reilly's Music Bar in NYC, where he lead a Celtic chorus of some of the most popular Irish drinking songs.
We're told the rapper and late-night host were Jimmy Fallon were downing Irish car bombs and singing classic joints.
