Desiigner made a guest appearance performing at the 2016 Austin City Limits Music Festival last night (Oct. 1)

The Brooklyn rapper came out with The Chiansmokers, to the surprise of the crowd, and performed his hit "Panda." Of course, the XXL Freshman went all the way in, like he always does, breaking the knob off with a roof-raising showing.

One concert goer wrote on Twitter about the show, "The Chainsmokers brought out Desiigner and he was a straight fool on stage."

The group later thanked the "Timmy Turner" rapper for coming through and rocking with them on Twitter posting, "Big ups to our Dude @lifeofdesiigner for coming through at ACL with us and shutting it down!"

For real though, Desiigner's live shows are some of the most energetic performances not seen since the likes of a younger Busta Rhymes. You can never say dude didn't bring it, 110 percent.

So what makes the turnt rapper tick? Def Jam recently released a mini-documentary sharing some of the origins and motivations of the G.O.O.D. Music MC.

“Did I always want to be a rapper? Nah,” he says in the nearly three minute clip. “I always seen myself as being an artist. Being able to create things and put things out there for people to enjoy and people to watch was just always me. And it’s love, I love it.”
