After blowing up internationally off just a couple of songs–one of them of course being his mega-popular platinum hit “White Iverson”–and touring the hemisphere with Justin Bieber, Post Malone is expanding his repertoire. He released a new mixtape, his first, called August 26 last month, and a new single and music video, “Go Flex.”

Last night, the Dallas rapper/singer took to the Jimmy Kimmel Live! stage to perform said single, backed by a live band, which was a pleasantly unique spin on the new banger. The original song does come chock full of guitar strings and synthesizers, and hearing it translate to the sonics of live instrumentation made for quite the rendition.

We’re still awaiting news and details on Malone’s major label debut–he signed to Republic Records last year–but get an idea of what to expect from it above.
