Post Malone Set to Perform at Times Square's TSX Stage

Post Malone is about to become the first artist to play a show on a permanent stage that's just been installed in Times Square.

The rapper/singer is set to perform Tuesday in the heart of NYC, and he'll be doing it on none other than the new TSX stage -- which has been getting worked over the past several months ... and which will have its big debut with Posty leading the way.

There's actually a billboard covering up the stage right now there in Times Square, teasing Post's concert -- with a plug of his forthcoming album, "Austin."

It's coming out next Friday, and we're told Post is expected to perform songs from his new project -- and probably some old hits of his as well. As far as how people are gonna see Post -- well, this billboard is actually going to open up and unveil the hidden TSX stage.

TSX Entertainment has actually been posting behind-the-scenes footage of the stage being built -- and it's pretty cool ... like we mentioned, this stands to be a staple in Times Square live entertainment going forward -- and it's cool they're having Post handling the debut.

We'll be watching ... 👀
