Post Malone closed out day three of the Voodoo Music + Arts Experience on Sunday.

In the two years since he played Voodoo Fest, Post Malone's career sure has changed. Back in 2017, he played a midday set on one of the smaller stages. This go-round, he not only headlined one of the three nights, but he closed out the famed New Orleans festival, now in its twenty-first year.

After his performance on Sunday, Posty wasn't done with New Orleans just yet. He took his partying to Bourbon St.

He hung-out with fans, and even jumped in on some performances with local musicians (as he's known to do). He sang on Tom Petty's "Mary Jane's Last Dance" and played drums on some other classics.
