Rich Chigga is making the most of his first trip to America.

After taking the stage at Rolling Loud festival (where he debuted a collaboration with XXXTENTACION and Keith Ape) he ordered a mariachi band using Postmates to surprise Post Malone with a cover of "Congratulations."

A short video clip of the event went viral over the weekend but now Rich Chigga has blessed us with a full video recap uploaded to his YouTube page with the title "How I surprised Post Malone with a mariachi band." What begins as a joke actually starts sounding pretty amazing when the harmonies hit around two minutes in. 

Watch above and look for the XXXTENTACION collab on Friday.
